I think Julie Bindel was right on the money actually with her "posh boy" comment.
A lot of the justifying of trans trampling all over women's rights is about how oppressed the poor TIMs are and how "cis" women should "check their privilege".
We all know that young white educated middle class males are one of the most privileged groups in society. The posh boy comment highlights that IMO. Julie Bindel has done a lot of work with street prostitutes - seeing these posh white men think they know anything at all about gender oppression must make her feel utter contempt for them.
It doesn't make them any less thuggish or threatening though.
