I think that Mermaids etc are right (ha, never thought I would type those words) that LGBA have focused disproportionately on fighting the TRA narrative rather than supporting LGB people generally
But actually, there's a good reason for fighting the TRA narrative, because trans activism is now the biggest threat to lesbian and gay people. Lesbians and gays have full legal rights now, including the right to marry, to have a sexual partner at age 16, to join the armed forces and so on. Their rights are protected in the Equality Act.
The people who are hellbent on attacking lesbian and gay people are trans activists. They do it in two ways: 1) by insisting that lesbians in particular should accept opposite-sex sexual partners, and that to refuse to do so is 'bigoted" and "transphobic" 2) by persuading lesbian and gay children and teenagers that they are "straight" members of the opposite sex, and leading them down a route that ends in sterilisation, infertility, a life-time of dangerous cross-sex hormones and the inability to orgasm.
What could be more homophobic than that?
