I wouldn't have become educated on these issues if it hadn't been on the main AIBU page and I am very glad that I have been educated on it (although the world was a lot simpler and less scary when I didn't understand what was going on.) It took me a while to get from thinking 'bigot' and 'transphobe' to actually read what they were saying but eventually the sensible posters, with their reason and (actually true) facts got through to me.
The thing is, I had been seeing a lot of these issues coming up in my real life (I'm a lesbian so I think we are on the forefront of seeing the new breed of entitled/creepy men identifying as lesbians, the erasure of women's spaces, lesbian orientation being seen as problematic and exclusionary of people with penises, younger lesbians being transed).
I think the reasons it took me so long to realise this are:
a) I'd known traditional transsexuals for 20 odd years, socialised with them, shared the ladies' toilets with them etc so felt I 'knew' from experience that there was no problem with this stuff. Even though I was starting to see the effects of the new wider meaning of trans coming through, it took quite a while to get my head round the fact that this was something completely different.
b) the gay press and LGBT social media lied and misrepresented constantly on this issue. Just as a small example, this story in the past week of Anne Ruzylo, a butch lesbian who was harassed and hounded out of her job as Women's Officer by two transactivists who also mocked how she wasn't as feminine as transwomen - I read an article in the gay press on this which presented it as a vulnerable transwoman getting a nasty bigot out and the story mentioned the gender identity and sexual orientation of everyone else in the story except Anne ie misleading their gay readership that this was about the LGBT 'community' standing up to 'anti-LGBT' people when it was about a butch lesbian being harassed, hounded and mocked.
c) this kind of discussion is being silenced pretty much everywhere else - It's getting slightly better now but I have learnt so much from some of the wise posters on Mumsnet. I used to believe (because I was deliberately led to believe it) that those opposing this 'progress' on trans issues were right-wing Christians who were anti-LGBT. I wouldn't have sought out opinions on a trans board on here because I wouldnt have thought there were any valid opinions for me to listen to.
