No, all bigots are definitely not male. In the real world (where I work)most of my workmates are bemused rather than disgusted by, for instance,gay partnership agreements whereas one female told me she hoped men who died from AIDS went "screaming in agony".
Another younger girl who definitely subscribes to a sort of 90s/60s lifestyle also subscribes to a "Send the buggers home" attitude to well, anybody not white and English.
Two examples, but the baddies are always more vehement and agressive than we Goodies.
