Interesting stuff, and I would agree that just about everything you mentioned was ignorant in some way, though I'd consider a Cinco de Mayo beerfest pretty harmless (don't know what a Japanese space wedding is or could possibly be). But, no, vaguely dismissing the entire free love/hippie/'60s movement as willful oppression of Native Americans indicates to me someone who has so immersed themselves in political correctness that they've melted the common sense synapses in their brain. If anything, the hippies were an homage to what they considered a better lifestyle. In some places I'm sure the movement occasionally crossed the line, whatever that line is, but not to the level of, say, the name "Redskins" -- at least not that I've read about. Honestly this is the first time I've ever seen anyone assert that '60s culture was a racist attempt to belittle Native Americans. Is that a common belief?
