Sorry, had to pop out. I wasn't intending to start a thread and run.
NeoFaust - Yes I have heard a small number of radical feminists say that all radical feminists should be lesbians. It doesn't appear to be a majority view though. Catherine MacKinnon for example, lives with a man.
There are a proportionaly large number of lesbians in radical feminism, but I think that is because the movement tends to be much more genuinely welcoming to lesbians, than other types of feminism such as liberal feminism are.
Choco - It does involve questioning gender stereotypes, and I would say more radical feminists don't shave, wear make up, etc, than women in the general population. But I have attended RadFem conferences, and there were some women wearing make up, heeled shoes with dresses, etc. Nobody cared. I think the key is understanding that patriarchy teaches us that we are supposed to dress and behave in a certain way, to constrict us and make us look "sexy". In reality, we should be able to dress however we want.
