Dave Chappelle -- Hartford Crowd Was Evil, White ... I Wanted to Pull -

Dave Chappelle is lashing out about the people who heckled him in Hartford, CT last week ... calling the crowd a bunch of "young, white alcoholics" and saying he wanted to pull a "reverse Kramer."

Chappelle took the stage at a show in Chicago last night ... and immediately went off on Hartford -- where he engaged in a nasty stand-off with the crowd after several loudmouthed fans heckled him during his set.

"I don't want anything bad to happen to the United States," Chappelle said ... "but if North Korea ever drops a nuclear bomb on this country, I swear to God I hope it lands in Hartford, Connecticut."

Chappelle then called the crowd "evil" ... and described them as a bunch of "young, white alcoholics."

"I wanted to pull a reverse Kramer and call them all crackers or something crazy like that."

Chappelle was obviously referring to the TMZ footage of Michael Richards during his insane N-bomb tirade at the Laugh Factory back in 2006.

In the end, Dave says the crowd in Hartford was lucky to see him "freak out" that night -- explaining, "That s**t's like being at a f**king tiger show the night Sigfried and Roy got their throats bit out by the tiger ... you don't go to see somebody be safe."
