While we are entertaining thoughts, entertain mine for a while:
What would have happened if 4 students wore the USA flag in a Latino-majority school on May 5th, say, 6 years back?
My guess is that it would have gone unnoticed.
Remember, while we love to think schools are in their own little world, untainted by the “big world out there”, it’s false. There is enough incendiary comments in the political environment, that it’s rather easy to escalate.
The school principal was “wrong” on asking the students to reverse their shirts because it was showing their flag (which they should be proud off), but he was “right” on asking them to reverse them because the political environment from which this steams wants to create that confrontation, and then have the excuse of saying, “Did you see what does dirty Mexicans* did to our kids?” and escalating it further.
