Rocker Pete Wentz has come to the defense of his pal Travis McCoy, insisting he did nothing wrong when he lashed out at a fan during a gig on Tuesday night. The Gym Class Heroes frontman was midway through a set with his band in St. Louis, Missouri, when McCoy took offense to an audience member who reportedly called him a "f---ing ignorant n---er."

McCoy invited the concert-goer onstage, but when the unnamed man lunged at the singer, he went on the attack - and whacked the fan on the head with a microphone.

The outburst resulted in McCoy's arrest on a third degree assault charge immediately after the concert.

But Wentz is furious at the "pathetic" fan and claims his friend was not the one in the wrong.

In a post on his online blog on Thursday, Wentz says, "you know what? you call my friend a "n_gger", i dont even give a f_ck what happens to you. i dont want to see you in this scene. i dont want to see you at shows. you are who we write songs about. you are who we think about when we hate... what a joke. you are f_cking pathetic and anyone that disagrees should put their white hood on too. i dont want your ticket money. i dont want your cd sales. id rather be poor and unknown. i am angrier than i have been in a long time. hate upon hate upon hate."

Meanwhile, Gym Class Heroes manager Bob McLynn has also spoken out in support of McCoy.

In a statement, he says, "Travis and Gym Class Heroes are anything but violent. It's amazing that in 2008 there are still people out there that would say such ignorant things."
