4 chan did a troll campaign years ago parodying college style activism by having people put up random pieces of paper that said only "it's ok to be white" around various college campuses. And sat back and munched popcorn while people were freaking the fuck out about an imagined KKK plot while others were pointing out that there is clearly nothing overtly wrong with that statement and anyone who doesn't think it's ok to be white is a racist. Very funny.

The idea was to slowly remove letters from the pieces of paper until they were just blank pieces of paper, then laugh as people freaked the fuck out over blank sheets of paper. Or random pieces of trash. Didn't go that far.

This was back during the "it's impossible to be racist towards white people" B's where people were confusing the academic idea of institutionalized racism with the actual common definition where it just means treating people differently because of their ancestry.
