I'm not judging these kids. I don't know them. But in this particular instance I think many of them behaved badly. It is pretty clear from the clips.
Even if Phillips was doing something wrong (and I don't believe he was) the kids should have stepped aside and let him continue his merry way. The kid who stood his ground acted like a jerk and the others acted like clowns.
Stepped aside? How the heck would thry know his thinking? He approached them and started drumming with people behind him filming. Are white maga kids supposed to run away from all confrontation now?
