I am trying to figure out whether you are angry at all transgender people or just certain individuals.
Mostly, I'm angry at the ideology being peddled. I'm angry at the effect it has on gay and lesbian people, as well as on females. And I'm very angry at the thoughtless echoing of "it's all about gender" and the rewriting of history and experience to try to frame it as gender instead of as sex.
Most of the transgender people I've met, I've very much liked and get along well with, including my own niece with whom I'm very close. I don't have a problem with anyone with gender dysphoria, nor do I have any objection to transvestites. I'm a fan of people wearing whatever they want and behaving in ways they're comfortable with provided they're not harming other people.
There've only been a couple of people who claim to be transgender who I've disliked. And in this case, I say 'claimed' because I cannot understand what they think transgender means. For example, there is one person whose spouse transitioned, and who now calls themselves transgender as a result of their spouse's actions... and their gender identity has nothing to do with sex or with gender but is out of a sci-fi universe. There's another that I dislike because they insisted that they feel like a woman inside, but have no dysphoria about their body at all, are very happy with their masculine physique and male genitals and beard, dressed in stereotypical male clothing... but demanded that they should have access to places where women were naked because they are "one of us" in some unspecified fashion, and they were brutish and aggressive and physically intimidating about it.
But the ideology... that makes me steam.
