You see, this just makes me even more confused than I was before about homosexuality/trans (as if there weren't enough 'new' sexualities to try to get my head around).
I'm straight and don't know many gay people so what I do know I've mainly gleaned from media, I guess.
I always understood that being gay or lesbian meant you were attracted to people of the same sex and that this was the way you were born and not a choice.
Assuming this understanding is correct, that attraction is based on biological sex, it's a hormonal and physical thing, and I don't see how an attraction to a trans person of the opposite sex who identified as your gender would even happen.
(Surely if you're attracted to either sex, you're bi or pan, whatever pan means.)
I have a colleague who was with her male partner for years and identified as straight. The partner transitioned to be a trans woman and she now considers herself a lesbian. I wouldn't say anything to her, or her partner but I do think wtf...
Implying that lesbians should be attracted to trans women is surely implying that lesbians have a choice over who they're attracted to.
And assuming isn't true, then isn't it a dangerous, slippery slope?
I would agree with live and let live in most day-to-day scenarios. I can't imagine a situation where I'd even discuss someone's sexuality with them. If someone brings it up, I'll just smile and nod. I'm not going to argue with them. If someone tells me they're trans, I'll be polite and use their preferred name but I won't make statements I don't believe in such as that there is no difference between a trans woman and a biological woman.
That is effectively what the OP is asking us to do and to me that's a line crossed. Believe what you want to believe but don't tell me what I have to believe. If I'm being polite, I'm doing no harm.
