Gc believe trans people can't change sex. I personally don't care, I'll still respect trans people's identity even so, it's the decent thing to do.
Knowing that people can’t change biological sex and respecting transpeople’s rights are not mutually exclusive. TRAs have framed it that way to squash debate. Don’t be fooled by that.
Are you religious? Do you only respect people who have the same religion and beliefs as you? It’s a bizarre world if you have to believe in a person’s God yourself in order to believe that that person is worthy of respect.
And equating GC with homophobia? Ironic considering the circumstances. A gay man being hounded out of pride by TRAs? Lesbian women being told that to not want to have PIV is transphobic?
Your motivation seems to be about being nice. And that’s fine. I’m with you. But don’t lie. You don’t believe that a person can change from XY to XX anymore than we do. That doesn’t mean you can’t be nice to transpeople. They deserve acceptance and freedom yes, lies no.
