Btw, your username always intrigues me. Why rosesandflowers? Because rose are flowers. Just wondering...
It's an old joke 
A woman in a sexual relationship with a transwoman is having heterosexual sex. They may want to call it "lesbian" but it isn't. Lesbian is not up for grabs. The definition is taken. And if contraception is or could be a consideration then you're not engaged in any form of homosexual sex.
So you would insist trans-inclusive lesbians find a new identity?
Are you another pioneer of describing people as homo/hetero romantic and then bisexual?
It's not transphobic to know that transwomen are, by definition, male, rosesandflowers.
They are indeed male, but women ... I mean, like I said, it's in the name. The fact that we're calling them trans women tells us that things are changing.
So the transactivists who claim they are women and therefore have periods?
The transactivists who claim they can breastfeed?
The transactivist who claimed that it’s transphobic to say they can’t get pregnant?
Could I have some context?
Just to be clear, you do mean trans activists that have penises?
Are they saying that it's transphobic to say it will never be possible, or just currently?
