It's a conversation that runs:
GI : 'we are all different, some of us have different needs, we are all worthy of respect and equality in however we express ourselves in a progressive world, and I want my needs to be catered for'.
Women, homosexual people etc: 'Great, completely agree. I'd like mine catered for too though, because I have needs too and they're also different to yours, so we're going to need single sex and mixed sex for us to have that equality, because we're both worthy of respect. Ending this provision works for you, but not me.'
GI: 'No, we have to do what I want and you mustn't challenge my beliefs because then I feel like I don't exist, so that means you can't have what you need, at all, and if you were a good person you wouldn't want to do anything except please and care for me. Your needs don't matter, and when I said respect and equality I wasn't talking about you. And I'll take you to court and get you a police record if you resist or say anything about this, and make sure everybody hates you! Plus <disturbed sexual violence threats>'
Women et al: 'er so what you want is an abusive relationship, and the answer is fuck no. The law actually says this <proves it>'
GI: 'Law is hate! The law is wrong! Only evil people want rights, privacy and dignity themselves that gets in the way of me doing what I want!'
It's not a rational conversation. Other people's existential crises are not a reason to deprive others of equality and freedom.
