Looked to me like most of the kids were just getting into the spirit and acting like teenagers act. A few did a tomahawk chop which is disrespectful in today's political climate, but they might have been clueless rather than mocking as they have seen countless tens of thousands doing it at Braves games. As far as the kid standing their smiling, he is under no obligation whatsoever to move aside for the more aggressive man.
The media in this country is so ******* dishonest, I can't imagine anybody falling for it. I'm reminded of the way they tried to turn a menacing 300 pound black thug into a helpless victim. Anybody with eyes could see the video of him grabbing the store clerk and tossing him aside like a rag doll, but the media had their race baiting narrative to sell so he was lionized as a "gentle giant" despite the fact he clearly wasn't.
