Not sure if it's okay to post about this here, but I'll try it.
I'm a girl (female), and god do I hate trannies with a passion.
There isn't anything inherent to being a woman or being a man. You can't FEEL like you're a woman, much like you can't FEEL like you're a separate species. Your body is not equipped with the ability to FEEL like being a woman. You can feel like you have TRAITS that we as a society have assumed to be more womanlike - you're more dependent, you're more emotional, you like wearing feminine clothing. That's completely fine - those are generally female traits, but there is nothing wrong with being a MAN and having those traits (you'd probably get weird looks for wearing a dress, but there's still nothing inherently wrong with that. It's just fabric.)
But thinking you're a woman? That's mental illness. You aren't a woman. You're a man with "feminine" traits, and there isn't anything wrong with that.
NOTHING that a man can feel is inherent to a woman. We piss and we shit just like a man would.
The reason that there's such a huge number of MTF trannies to FTM ones is that women with masculine traits aren't judged as harshly as men who have female traits. If a man expresses emotion it's seen as weakness, but if a woman wears male's clothing nobody bats an eye. There's nothing unnatural about a woman having these traits.
And there's a reason that a disproportionate amount of men that start transitioning end up more miserable than before. They're not successful. They still look and sound like men. They didn't turn out to be the idealized female they've created for themselves. Many of them end up killing themselves.
In short, I think that this phenomenon is part men not being allowed to have feminine qualities, part fetishization of women in general, and part mental illness.
I'm sorry that this post was a jumbled mess, but I don't care to fix it. Just know that trannies are hated by both men and women.
