It was, but there were people bitching about it. It may be an unconventional way to show it but if you look at Eminem’s album released in 2004 the second track was Mosh.

“Stomp, push, shove, mush, Fuck Bush, until they bring our troops home”

“Let the president answer a higher anarchy Strap him with an Ak-47, let him go, fight his own war Let him impress daddy that way No more blood for oil, we got our own battles to fight on our own soil No more psychological warfare, to trick us to thinking that we ain’t loyal If we don’t serve our own country, we’re patronizing a hero Look in his eyes its all lies The stars and stripes, they’ve been swiped, washed out and wiped And replaced with his own face, Mosh now or die If I get sniped tonight you know why, Cause I told you to fight.”
