Like LGBT rights activists, feminist campaigners are often dismissed as over-sensitive, irrational 'extremists'. Even to many relatively liberal people, feminism appears to be a dirty word - a brush you just don't want to tar yourself with.
"I call myself a feminist when people ask me if I am, and of course I am 'cause it's about equality, so I hope everyone is. You know you're working in a patriarchal society when the word feminist has a weird connotation." ~Ellen Page
