With regards the fact that Samantha Bee still has a job on television while Roseanne Barr does not, I see four possibilities.
1. Some unknown authority has issued a secret decree to the effect that an offensive sexist slur is less egregious than an offensive racist slur.
2. The leadership at TBS lack the courage and conviction of the leadership at ABC.
3. An educated progressive immigrant can get away with things that an native-born high-school dropout cannot.
4. Some combination of the above.
I am no fan of Barr or her politics, and I find Bee’s show rather more entertaining than Roseanne’s ever was, even though Samantha and I roost on distant squares of the political plane.
That said, I find both sets of comments equally loathsome, and if one of these two comedians deserves to be collecting unemployment for her remarks, both do.
