From: An Outraged California Reader [Email him]
This disgusting poster (gag me!) is from the same California high school that sent American students home for wearing American flag t-shirts on Cinco de Mayo, 2010.
The decision was upheld on the "heckler's veto" grounds that the Mexican students might get violent.
The poster below doesn't just support immigration, it supports illegal immigration—the "immigrants' rights" presenter SIREN is a Bay Area group that's been supporting illegals since 1986.
