Honestly don’t know what you going on about. Villanueva is not Mexican, not a “chicano”, and was never part of La Raza. Nor is there anything wrong or disqualifying Mexican American, however Villanueva is half polish half Polish, half Puerto Rican.
Holy crap, you’re right. I usually fact-check these things; I got lazy because I’ve been sickly lately, and I mixed people up.
Bustamante (SHAME ON ME FOR MIXING THEM UP BASED ON HISPANIC LAST NAMES) is the California “rising star” I remember from years ago who was MechA.
