Stop making fun of the French for losing the battle?
LOL. Cinco de Mayo is an American Holiday that uses Mexican stereotypes. I'm assuming that they're not going to adhere to those stereotypes any longer.
....Well, it depends. "Greek" also means frats and sororities.
No. It doesn't. Frats/sororites aren't don't pander to specific races as Cinco de Mayo does. They're not a "race", nor do all of them follow the stereotypes that people hear about.
