is it ok to “identify as another gender” irl?

Have you considered talking to gay people to see if it's actually a choice they make?

"But I am actually being entirely serious, while my beliefs are being all but openly bashed."
You fundamentally misunderstood my point here. You're advocating for other people to be tolerant of your beliefs, and yet you at the same time are calling gay people abominations. If I were to call you an abomination for your beliefs, would you see that as fair? If not, why do you then also think it's fair for a gay person to be called an abomination? Also, if you DID understand what I said, then your wording here seems to imply that you don't think gay people are actually serious, in which case I need a citation.

" I could call your beliefs the same thing - it's rather an opinion."
OK, so let's go through the list; my beliefs are intolerant of someone like you, so I guess in that sense sure, I'm intolerant. However, what about my beliefs are unfounded? My beliefs, or lack thereof, stem from a lack of evidence. Is a lack of evidence unfounded in your eyes?

"On another note, I think my beliefs aren't unfounded if they come straight from a book that cites the laws God gave man..."
They are according to you, but if I went and talked to a Muslim they'd probably say that those laws are bullshit and that the real ones were given to man in the Quran. The divinity of these laws is predicated on the existence of your God, so until you can prove to me that your God exists, I will continue to call them totally unfounded.

"(bronze age? Last I checked (very recently), Christianity still has millions of followers worldwide and is one of the largest existing religions, and that's anything but bronze age)"
In fact, Christianity has BILLIONS of followers worldwide and it IS the largest existing religion. But that's not what I mean by bronze-age. I mean that it's a bronze-age belief in the sense that it was created around that time and is, thus, outdated and incompatible with modern ideals.

"My problem is with what others believe about the morality of being gay or whatnot, not the person themselves. There are certainly many kind and intelligent people who happen to be gay."
Really? So despite the fact that you said you believed being gay to be an abomination, you still maintain that you do not have any problem with the persons themselves? Either you're terrible at articulating yourself or that's a huge logical inconsistency on your part.

"Yet again, I could just dismiss your own atheist beliefs as laughable; it goes two ways."
Do you believe that disbelief in your God is laughable? How so?

"However, a flat earth has been disproved by photos and modern science, and a "flying spaghetti monster" wouldn't exist since spaghetti is an inanimate object."
I won't disagree with your first point, but in regards to your latter point, it's one of the weakest takedowns of the argument I've ever seen. Yes, spaghetti IS an inanimate object, but the existence of spaghetti and the existence of a flying spaghetti monster are mutually exclusive concepts. You could have one and also still have the other.

"I see proof of God's existence in nature - the complexity of things, the way everything just turned out the way it did, the way how Earth happens to somehow be the only inhabitable planet we know of (even with technology of today, the estimated number of planets in a galaxy is such that only an extremely small percentage, if even any at all, would be inhabitable)"
Sure, everything happened the way it did, but had it not happened the way it did, we wouldn't be here to observe that it didn't happen that way. And things DIDN'T happen the way they did with earth for billions and billions of years after the creation of the universe. As for your claim that we are the only theoretically habitable planet in our entire galaxy, that would still mean that there could be hundreds of billions of habitable planets. Why? Because believe it or not, the universe exists OUTSIDE of our galaxy. There are 100 billion galaxies (Source) so even if only 1 in 10 galaxies had a planet capable of harboring life, there would be tens of billions of planets capable of doing so in the universe.
And even with ALL of that said, why is it that us being unique and special is an argument for the existence of YOUR God? Why not Allah? Why not the Greek Gods? Why not some god no one knows about? Even if you want to claim all of this is evidence of a divine creator you then need to tell me why yours is so damn compelling over the rest of them.

"even how we as humans have conscious thoughts, the most intricate of any so far discovered species. I doubt that all those things would have come into being from an accident, a Big Bang, or the heating of the universe."
Well, luckily, how you FEEL about things has no bearing in fact. When I was young, I did not feel like it was possible for something to be in two places at once, and yet with the double slit experiment scientist have proved that in fact on a quantum level, things CAN be in two places at once. The fact that you feel as if this is impossible to have come about is not in it of itself evidence that it didn't happen this way because of an "accident" or the Big Bang.

"our definition of common sense may be something that I don't have, but you saying I lack any decency is the unfounded thing here.
"
I would say that you calling the act of being gay an "abomination" shows a profound lack in decency. Of course that's ultimately subjective but so is morality as a whole, so the point is moot. I would also call your assertion that being gay is a choice to be lacking in decency, as well as being totally unfounded in any science I've ever heard. Could you please cite the scientific literature that you used to come to the conclusion that gay people choose to be the way they are?

I think I covered just about everything

I think straights choose to become straight, because I've talked to plenty of straights and they say they "started liking girls" at a point. \s

Just because they became gay doesn't mean they chose it, it means they simply weren't sure of their sexuality. What motivation would anyone have to voluntarily be gay? Do you think you could become gay if you tried hard enough, since it's apparently a choice?

They're abnormalities but they still exist. Just because they're rare doesn't mean they should be completely disregarded, just like how people with 9 or 11 fingers shouldn't be told that they have 10 fingers when they actually don't.

you missed the point. if i asked you how many fingers a person has, you would certainly say "10" and not "10 but in extremely unlikely cases people can have more or less". same goes here.

If someone was asked how many fingers a person had, and you answered "10 fingers", then that's fine. However, if you answered "THERE IS ONE NUMBER OF FINGERS, AND THAT IS 10!!!", which is the equivalent of what spikejumper and rtef did, then it would be a bit misleading, no? Insisting and insisting that there are only 2 genders is effectively telling intersex people that they don't exist. Likewise, if someone casually asked me how many genders there are and I was rushed for time, I would probably say 2 (unless I had time to elaborate to them), but I would never answer "there are only 2 genders, absolutely nothing more".
