I'm a man, so can never even be a feminist, much less a radical one. But experience of looking after children, being supported by and supporting women who do, makes me wonder why everyone doesn't start wearing a Fuck the Patrix T-shirt the moment the Bounty pack arrives, seems no other way of explaining the manifest oppression of mothers and children all around me. And I probably agree, however much I try simply to change what is there, that ultimately you can't build anything truly better unless you knock the whole bloody mess down and start again. I'd be first against the wall come the revolution, but maybe my spirit would see a better world.
I'm also an academic, and am concerned by this thread. The seminar leader defending free speech is shit-seminars are professional environments, not laddish aggression sessions. Sue him-most academics are sued unjustly, be good to have one up against the wall fairly for once.
On the PhD supervisor there are explanations (I'm not defending, just saying there are) which are not ideological. I've seen supervisors do nothing but put a line through work and say 'go to library', others whose students always leave the room in tears (a female colleague of mine was particularly guilty of this-believing women needed more toughening to survive) and others who are all sweety nice but ineffectual. It's a complex thing to do-it demands an understanding of who you are dealing with, a negotiation of intellectual and personal difference, and being the critical eye, yet no special training at all is given. I've always grilled my students very, very hard and aggressively on framing even when I agree with them (in fcat more so when I agree because I need to be sure they are not trying to please) because if the framing is not believed in by the student then work will be wasted or the project be abandoned. It may be your (young) supervisor is doing this but failing to explain it at a basic level. Or he may just be a cock, I've no idea, but you need to ask and seek alternative supervision if not.
