Sure, and you could get jailed for eating pork or beef in some places. Or even for having your face uncovered. But here in the US that doesn't happen. (I was speaking primarily to the US since I was replying to the "melting pot" post.) So how do you decide which celebrations of differences are real and which are artificial? Is Cinco de Mayo real or artificial? How about St. Patrick's Day? Bidil? The Knights of Columbus? The Portland Gay Men's Choir?
