Joan Rivers thinks everyone is way too uptight about hurling racial and other epithets ... so she hurled them against Italians, Blacks, Jews, Chinese, gays and don't forget the Irish.
And speaking of the Irish, Joan blanched at MSNBC's firing of Alec Baldwin for going on a homophobic tirade.
We got Joan outside of Canter's Deli in L.A. -- where lots of Jews hang out.
We didn't bleep anything in the clip, because all you'd hear is a bleep. It's pretty shocking. Take a listen.
