Tweet: "Happy white peoples independence day the slaves weren't free but I'm sure they enjoyed fireworks.”

The politically incorrect comedian has never shied away from racial humor. But conservatives across the nation viewed his Independence Day tweet as both unpatriotic and (brace yourself) racist. Several of Rock’s industry friends like Don Cheadle came to his defense, but the backlash created more pyrotechnics than the Macy’s 4th of July Fireworks show. Get over it, America.
