I totally agree with what you said, but remember this is rock and metal. The main listeners are men and most men are attracted to women. So when you say, "Why when is it when theirs a band using the frontman's good looks to get popular, no one cares. But when it's a chick everyone is pissed" It's because most guys aren't attracted to the male singer, so they don't G.A.F. But most of us are attracted to females and everyone on both sides of the fence(Side 1=people not in the band. Side 2=Band using female as a way to attract attention) knows that, and Side 2 uses as it as a way to attract attention. Not all bands with a female/females do this but many do, and in metal/rock musicality is valued over how you look, so people get pissed when this happens.
