That's a brilliant letter.
It takes a strong stomach to tell feminists who have spent a lifetime fighting for the rights of women that they are, in fact, hateful bigots but, rather than engage with the questions they raise, many men seem happy to do just that. And a glance at social media quickly reveals that they often do so in the most revolting ways.
Sending tweets to women instructing them to shut up and suck your f*ing dick isn’t progressive, no matter how fashionable your haircut or skinny your jeans.
I do wonder if the men, reveling in the chance to mansplain, hector and abuse women while pretending it's "to defend the most vulnerable women of all", think we don't notice that the only women they care about are those born with penises. Funny, that.
