I think the wingnuts are just trying to make the best of a situation that could have been a goldmine for them but wasn’t, thanks to the effective action of the school authorities.
Imagine if the boys had not been reprimanded and they had gotten their asses kicked by a bunch of Hispanic-American students. That would have made the wingnuts’ day. Imagine the outrage, the foaming at the mouth, the calls for sending “violent” “gangster-like” Mexican highschoolers “back to their country”, even if they were American citizens.
The outrage is just rage at a missed opportunity.
