Firstly, what is so effeminate about Panda Bear? He's a guy in his 20s. That's what just about every single guy friend of mine and I look like. He's just a dude in a t shirt.
Well, if you and your friends are into the effeminate look, that's up to you. Do you guys wear panda ears? That seems effeminate. Or maybe he's just into furries...
And as for the Judas Priest guy... haha, are you serious? That guy looks like a moron. He's either a biker or just some loser trying to look really badass because underneath he must have some serious doubts about how manly or tough he is. All of the manliest, toughest dudes I know don't look a thing like this. On the other hand, the ex-convicts I know do. If it's cool to look like you just walked straight out of a hell's angels meet up or a 5 year prison stay I guess this is cool too.
He's a biker, rides his Harley on stage, never been in prison.

Funny how all the emo/sensitive/alternative guys play this card. "They must lack self-confidence in their manhood." Probably because they don't know how to express manliness, completely lacking it and all.
So is Chopin only for women and homosexuals? Mozart? He certainly looks pretty effeminate and the music sure as heck is as far from metal as you could imagine.
Actually, it's closer to metal than you can imagine, especially when compared to this emo/alternative stuff. So, if you want to engage in a discussion of music theory and analyze various aspects of music, I'm game.
Bob Dylan? Radiohead?

Dylan is definitely a fag (in the non-homosexual sense of the term). I don't know anything about radiohead.
The irony of presenting a picture of a guy who looks like he just left some perverted homosexual s & m party and then claiming that these guys look effeminate is thick.

I dunno. They look pretty poofy to me.
We haven't even addressed the fact that Halford is a better singer in terms of range, sustain, fullness of voice, and the basics of singing on key.
