My son's high school has a MEChA club and my son knows the President well. The club is little more than a meeting place for upper middle class Mexican-American kids specializing in cooking and Salsa Dancing.
That, of course, is the insidious part of it. These kids will go off to college and being new and lonely join MEChA at university. And as you can see the College based MEChA has a more racist world view. I'm sure the puppet masters like nothing better than turning these kids into haters of the kids they grew up with.
