They all have. Someone on rsp mentioned why there's a reason lesbian subs are being taken over and gay ones are staying the same. Basically it's because women are more easily bullied. But they pointed out that men socialise innately by hierarchy where women don't. And what happens is that a trans woman, still being a man, applies the same male hierarchy in a group of women. Thus they take over, because... That's just how it works.

In gay groups nobody minds the transman because they know where on the hierarchy they stand, and the transman does too. This stuff isn't even conscious for most but it happens.
