You’re right it’s the lack of acknowledgement.
Corbyn, Sultana and their bunch of merry men are the same (bar Adnan Hussain, who seems a decent type and has signed the motion calling for urgency and proper action in the inquiry).
Corbyn did a post about Gisele Pelicot, probably because the men involved were white European majority (and NOBODY is saying white men can’t be abusers, or that they don’t abuse far too much) - but I don’t think he has ever once commented on the mass rape and abuse of girls in his own country.
Honestly right wing men pose certain issues to feminism but do not underestimate the arrogance, dismissiveness and contempt that the left wing men have for women. In many ways it’s worse as it’s far more insidious and gaslighty and hidden under ‘bigotry’ and ‘racism’ and ‘greater good’.
