Definitely has a baby face, but how often do rioters go after each other? Had he not been carrying an M&P and been playing cop, he probably would have been ignored.
If he was a target simply for being white, then how/why did Groskreutz not get attacked too? Liek you said, Rittenhouse was ill-prepared for reality. I think the first "attack" by a mentally ill man was more than he was ready for, and it spiraled out of control very quickly, turning him into an active shooter (which he kind of was) who people were willing to risk their lives to stop.
IMHO, going on the attack with a skateboard against an M&P is an act of "what have I got to lose at this point?" desperation. Exactly what we want teachers to do in an active shooter sitch at a school.
At the risk of repetition, "Let's roll" comes to mind.
