I think the classic feminist trope about wanting to have multiple male partners is more a way for psychos to promote abortion rights than any kind of promotion of equal rights.
The more sexual partners a woman has the more likely she is, inevitably, to get knocked up. IMHO, killing a baby because some psycho thinks banging lots of guys makes her equal is a bit twisted.
Maybe a feminist-brain makes it a good idea, but I fail to see how being slutty makes a woman equal to a man. Doesn’t really make sense to me.
