Honestly? I don't like most of 'em. I have an intense dislike of lip syncing and that is what the vast majority of drag shows are. For the most part, I dislike the overly flamboyant, probably for much the same reason that African Americans aren't fond of black face - it's a caricature or what we are.
Now the very few drag artists that actually sing, or do comedy, I'm all for that . . .
