Well-said on all counts, I think. My only point of disagreement (reassurance?) is that feminism is definitely not monolithic - there's a reason that a lot of people talk about 'feminisms'. I'd go so far as to say that anyone who expects you to agree with anything that any particular feminist says is doing it wrong. Although obviously you should probably agree with them when they're right. ;)

It's always difficult to know when to shut up about politics and when not to, no?
