If you’re seriously not understanding why anyone who can be pro trans rights can also see that a penis is not the same as a vulva, well you clearly have a very black and white view on life and it’s pointless having a conversation about it.
The point is, that that IS what the TRAs are telling everyone. That it is 100% no questions asked, complete agreement, man is woman, penis is female, up is down. Whatever anyone says is true and entitles them to every benefit, place or space reserved for the sex they claim to be (and TRA ideology not only says they now are that sex, but that they have always been it)
And if you disagree with ANY of it, you are a bigot and a transphobe.
There is no room for being "pro trans" and only believing/agreeing with some parts of it, or saying someone is not "genuine" like Yaniv, according to them.
