They are female. I don't care if they acknowledge it or not as it doesn't change that they remain female. I am not going to lie for anyone, including these adult human females.

Biologically, yes. But socially they are men. For instance, I am a cis woman and so are most GC people (although they don't use the term cis). Although we are both biologically female I don't agree with many of the things they say about trans women. I don't feel trans women are oppressing me. But I don't go on Ovarit and other GC spaces telling GCs they aren't oppressed by trans women. It's their spaces. They can speak about the oppression they face as GC women, as long as they don't speak for me and cis women who don't want to be spoken for. Trans men should be able to discuss their oppression without cis women interfering.

They experience it as female people as female people are the only one who can menstruate. Had they been men they would never have menstruated even once in their life as men never menstruate.

They experience periods as men.

Me hating getting periods has an emotional layer to it too as I hate knowing I can get pregnant. Female people can have all sorts of feelings (including wanting to be a man), and it doesn't make anyone a man.

A trans person's experience with periods and a cis person's experience with periods are entirely different.

I wouldn't. Many adult human males who want to women are AGP though but that's just a fact, just like many adult human females who want to be men are AAP. I am not going to ignore facts just because it hurt their feelings.

Many would though. For example, there is a thread on Ovarit titled TIFs need to notice how little TIMs actually care about them.... They literally discuss how trans men only ever complain about trans women harassing them and not trans men and when they point it out they are silenced. GC has numerous times made posts about trans women talking over trans men, even on the old GC sub. Yet somehow its OK for cis women to talk over trans men, and when trans men point it out, they are called misogynists. It's a double standard. If you support trans men calling people out, you can't decide which groups they are allowed to call out and which groups they aren't allowed to call out.
