No. Transwomen are adult human males, therefore they are men.
You're arguing a strict "biological category."
I'm arguing that mammals cannot change sex, which is a biological fact.
The only biological purpose for an orgasm--for ejaculation--is to drive you to impregnate women. Your penis serves only one biological imperative, so if you are not sticking it in a woman's vagina, you are acting outside of your biological category in the exact same way that you are bizarrely arguing transgendered people are doing.
Every single sex act with an infertile woman, or a woman on the Pill, or a woman post menopause, or a penis with a franga on it, or a penis that is withdrawn before ejaculation, or an oral sex act, or a jerking off, is 'acting outside of your biological category' if that's what
you imagine 'acting outside your biological category' to mean or why it's important to you.
I don't care if you or anybody 'acts outside your biological category' and I never have. What I do care about is the cultural and legal proscriptions trans activists have wielded to criminalise or cancel somebody who "misgenders" somebody else, to bully lesbians into having sex with men with penises who call themselves women, to invade single-sex spaces as if single-sex spaces were single-gender spaces, to give puberty blockers with unknown long-term effects to children, to make a mockery of women's and girl's sport.
There are "transwomen"--biological men with penises--who are in relationships with women--actual women, and they call themselves a lesbian couple. So when this man has penis-in-vagina sex with his girlfriend, he thinks: this is so lesbian and she thinks: this is so lesbian
and they want me to think the same thing.
