Babs03 this is not about sexuality. Many transwomen claim to be lesbians, who are attracted to women. So basically they are straight men. The idea that transwomen are gay men who are more 'female' than male is well out of date.
Mostly it seems to be about power. If a lesbian (obviously a woman who is attracted to other women) doesn't want to have sex with a transwoman (a man) she risks being accused of transphobia and is abused.
Straight men claiming to be transwomen when accused of crimes so they can get into women's prisons are another case in point. If someone has sexually assaulted women, that does suggest that their sexuality is (perverted) heterosexual, and more to the point suggests that they should never be locked up with female prisoners.
Many gay people are sick of their sexuality being conflated with the trans movement, and of the T in LGBT(QI+). Gender is about the way society expects people to behave, based on their sex. Sex is biologically determined. Sexuality is about attraction. They are very different terms, but are increasingly being conflated, perhaps to confuse people.
Taking over the language is always a way that dictators get power. Ask a trans activist what a woman is, and if you get an answer at all, it will be a million miles from the definition that has served us all for millennia - an adult human female. Instead, women are 'vagina havers', 'cervix havers', 'birth givers' and so on. Or worse 'non-transwomen', 'non-men'. The male is always centralised, and women seen in terms of our relationship to that. I fear for our daughters and granddaughters.
