Society has sadly become much more homophobic in recent years.
Yes, I agree - the rise in gender ideology undermines homosexuality to the point where the very definition has been queered to mean something else.
So whereas previously, everyone knew what it meant to be a gay person and that sexual orientation couldn't be changed and gay people were exclusively attracted to their own biological sex, now even Stonewall and many other LGBT organisations who used to advocate for gay rights are promoting the notion that some lesbians have biologically male bodies, which obviously undermines the whole idea that sexual orientation is about biological sex.
So now people are told (including by Stonewall) that lesbians can actually cope with penises (and often that there is something wrong with them and they may need psychological help for past trauma, etc if they can't entertain the idea of sleeping with someone with a penis), then it's hard for the general population to understand this completely new and confusing version of homosexuality.
I hear a lot more homophobia now from people, often in the context of advocating for gender ideology, but also more generally. And I think that spills over from homosexuality being discussed in far more confusing and vague, non-committal terms than it was even five years ago, when it was clear that lesbians can't - and shouldn't - be turned.
Now Stonewall have started pushing out the idea that lesbians can change to acclimatise to sleeping with biological makes if they really try, I feel it's given heterosexual men the exact ammunition they needed to use that argument to harass lesbians, because that's what "experts" on lesbianism such as Stonewall say about lesbianism.
I had a pansexual woman tell me that my being a lesbian was very closed-minded and exclusionary at a women's group recently. It's common to view homosexuality as transphobic now and people with homophobic views are empowered by that and becoming more vocal about it.
