Did Trayvon think George was a faggot cruising for young tail, and decide to pummel him? Even so, teenagers should leave the queers alone.
Exactly.
According to his gf Jabba, St. Travon referred to George as a "creepy ass-cracker" watching him.
Jaba teased St. Travon about getting raped.
At that point St. Travon decided to seek out George and do a beat down for dissing his manhood.
Probably with encouragement from Jabba.
St. Travon's homophobia was the motive for assaulting George.
