Women can’t sing rock?

Funny, I was just having this conversation with my brother and sister yesterday. Our discussion sprang from by my brother’s band’s guitarist’s opinion that women can’t sing rock. I agree with what Jack says about disliking female vocals having more to do with negative connotations. The preconception exists that a female vocalist means “chick rock” of something else that’s not just “rock.” I find the notion prejudiced. I mean, not all female bands can be stark raving mad man-haters who want nothing else than to destroy the entire male sex, can they?
