If you haven't seen this Shirley Q. Liquor act, it's done by Chuck Knipp, a white gay man who dresses up as a straight Black woman (in blackface). This character is an "ignunt" "happy-go-lucky mother of 19 children" who, according to Knipp, "is not afraid to embrace every cultural stereotype and subvert them for her own purpose". Knipp portrays her as an irresponsible, incoherent alcoholic, and if you look through the rest of the YouTube library of Shirley Q. Liquor, there's a whole lot of grossness involved. Read a good article about the performance by Keith Boykin.
I seriously hope Knipp isn't ignunt enough himself to think that he's doing any sort of favor to the Black or the gay communities. As a gay man he should understand thing or two about context. When such a performance is done (in fact, when any performance is done), every joke, every line, every word is itself a symbol designed to bring certain images to the audience's mind. This applies to simple words like "banana" making people think of the fruit (or a penis, I guess) to the symbol of blackface making people think of those old Vaudeville acts that used it to demean Black people. It applies to Eddie Murphy's homophobic "comedy" in order to justify every negative stereotype of gay people out there to Knipp telling jokes that sound like pages out of the Republican's old Southern Strategy.
Moral of the story is that Knipp is bringing more baggage into his act than he chooses to acknowledge. While it's theoretically possible that it could be funny to speak poorly, wear bad make-up, or make tired jokes about waking up late, when done by a white man performing in blackface, its subtext is white supremacy. Keith Boykin says:
If the results are to be believed, just 4 percent think the site needs "less offensive" humor. That may tell you a lot about Knipp's audience.
And this isn't helping out the pervasive stereotype that gay people are rich, white, elitist racists, either, which is probably why the National Gay and Lesbian Task Force is against the performance as well. It's not to hard to see the effect of something like this on the ability of voters, judges, and Congress members to buy into silly arguments about how gays are too rich to need equality, too snooty to condescend to give back.
Take a minute to sign the petition against Knipp's performance.
