Most people also wouldn't want to be the person who does this, because most of us know we don't have something to offer every single group and therefore it's inappropriate for us to be there. That's something I really can't wrap my head around, in the example from Reddit - what did that 30 odd man think he could offer a group for female rape survivors? How does it not cross your mind that you don't have any role of any value whatsoever in attending a group like that? And, the part that makes me suspicious - given he can't relate to those experiences, what is it, exactly, that he is getting out of attending that group? That's where it gets sinister for me. Transwomen wanting to go to groups for rape survivors, mothers, breastfeeders, whatever...it's creepy.
