As many of you will remember, the Radfem 2012 conference in London was explicitly open only to born women and consequently attracted lots of condemnation and anger from people who saw this as transphobic. It was kicked out of its original venue at Conway Hall and went underground (very successfully in the end).
This year Radfem 2013 has not explicitly banned transwomen... but instead it's come under attack from Men's Rights Activists, who have staged a demo at the planned venue, the London Irish Centre, while making lots of unpleasant and ridiculous claims about how radical feminists want to murder small boys and the like. As a result the venue is threatening to cancel the booking.

I have mixed feelings about the whole trans issue but have no hesitation in declaring the MRAs utter misogynist knobbers and am disappointed the London Irish Centre has seemingly caved into them.
