lack of respect in the world these days, need advice BAD

[Johny5]

wow, so just as you think people can't get anymore fucking lame...

my girl was in her last period today. some faggot shit told her that he talked to me (note: i don't even know this SOPHMORE) and that what they did last night was alright as a sexual reference. she ignored him. he proceeded to steal a $5 out of her purse and put it in his pants. at the end of class he asked if she wanted it back, she did because its fucking money and he had no right to take it. at that point he gave it back and felt her tit.

now, please, i'm not much of a fighter. but i've been thinking, i've got quite a few big big friends (i'm a very small guy myself) and would it be wrong for all of us to whoop his ass? thats about as fair as a big guy harassing a fucking FEMALE, would you not agree? should i let this pass? i'm so mad right now i'm just shaking. i want to do something so bad and i guess i need unbiased opinions on either the consequences or the glory of watching that motherfucker go down. thanks.
