Drag can and does contain shock humour, like Divine definitely did a fair amount of, but most drag isn't based in shock humour, which is what the other poster was saying. Some of the more recent famous drag queens are known for their insult comedy... and there are definitely a lot of drag queens who do some very dirty jokes, but even the most shocking thing about RuPaul these days is that she's fine with fracking and still hasn't forgiven Courtney Act for rightfully calling her out on transphobia.

Like if you want shock drag queens, you really have to go looking for them. It would be very difficult to accidentally stumble into a show that resembles Divine during her John Waters days. You're way more likely to find a trained dancer and their own dance-pop album.
