Man, I dunno, it was the first semester. Maybe word about CFVY's skills hadn't reached the first-years yet 'cause everyone was too busy sticking to their own cliques.

And racists generally don't care who the person they're being racist toward is. Cardin had his teammates there with him, and apparently the rest of CFVY had lunch during a different period (probably due to whatever classes they were taking), so they probably thought they could intimidate her with 4-on-1. With Cardin's personality, I wouldn't be surprised if shoving him away and telling him to knock it off would lead to a fight. He stood up, fist clenched and growling, in the middle of fuckin' class when Pyrrha and Blake showed him up. Dude's got an attitude problem and seems to think it's alright if his team can gang up on someone like they did with Jaune in Forever Fall.
