I knew a few trans people as friends of friends when I was younger and lived in the city, but not these days except very remotely, through work. I will also readily admit that I've been ignorant of the ongoing struggles for trans representation and recognition, because those people never brought it up back then. And as a result I've accidentally asked some tactless questions on here that, had I really sat down and listened, I would not have needed to ask.
I try to engage with as much diverse media as I can, so seeing the push for more (and better) trans representation on TV and in film in that trailer struck me as a very positive thing. Because in my friends and extended friends circle I can talk to a black person, a queer person, and so on... but I can't talk to a trans person, because I don't think I know any.
