Hispanic students wear Mexican flags. American students wear American flags. Oh, no! The potential for violence!
Attention. All students wearing American flag t-shirts must turn them inside out to prevent.. to prevent... to prevent...
well, to prevent the Hispanic kids from being violent, apparently. I guess the school administrators didn't think that the Hispanic kids had the ability to just appreciate everyone's freedom of speech or something. Sounds vaguely racist to me.
Oh, by the way, this is in California, not Mexico. Can't have American flags in America now. Might make foreigners get violent. The sad thing is that the Ninth Circus Court of Appeals upheld this. Hopefully we'll see some sanity from the SCOTUS soon.
I've heard this called the heckler veto. "Your speech is making me violent so you need to stop".
