Trans people are not a culture. Trans is an umbrella term for several different groups many of which don't agree or want to be with each other but somehow have. Part of the issue is that the difficulty in discussing the perverts and risks such without hitting into Stonewall's definition of trans.
Seriously, Stonewall defines trans as "an umbrella term to describe people whose gender is not the same as, or does not sit comfortably with, the sex they were assigned at birth. Trans people may describe themselves using one or more of a wide variety of terms, including (but not limited to) Transgender, Transsexual, Gender-queer (GQ), Gender-fluid, Non-binary, Gender-variant, Crossdresser, Genderless, Agender, Nongender, Third gender, Two-spirit, Bi-gender, Trans man, Trans woman,Trans masculine, Trans feminine and Neutrois." I'm sure most can see why some of those might have an issue with being associated with each other. It's pretty weird and uncomfortable to have Two-Spirit alongside crossdressers. Most people are uncomfortable with some aspect of the gender associated with their sex. It's a very unclear term right now.
And then we have the other people with gender dysphoria, which used to be defining factor of being trans, being told mostly by people without dysphoria both that we need to identify as trans or we're harming the cause and trans people by not being out and proud and we also can't be trans and discuss being dysphoric or we're harming the cause and trans people by associating them with a mental illness. We're damned if we and damned if we don't and it's a great mindfuckery.
I grew up in the Bible Belt of the US - the kind of place that the year I left had a KKK rally - and yes, racist and sexist and homophobic people question themselves when pushed sometimes. If they didn't, there wouldn't be any progress at all. People change, none of us born bastions of ethics, it's an ongoing effort. I've changed my mind a lot in my life. There are sorry groups at many US Prides full of (some formerly, some currently) religious people who used to say horrible stuff who stand between us and the still hateful people. They were at my first Pride and it was nice. I've had far more issues with the "left" who think they're always the better people and getting them to consider whether they could be wrong. I do wonder if the people who have sent me rape and death threats ever wonder if they're wrong. Only one person to suicide bait me has ever apologized and that was many years ago. I still like to think so, I don't think being a female dysphoric person who openly talks about it and wanting female to signify my body no matter how I feel or identify is such a horrible thing but I guess I could be wrong.
