It really depends if it's used offensively or as part of a broader pattern were somebody has more power than another person, and the one with the least power does such "jokes" - I don't think the "meek" using that technique to somehow get back at the dominant is correlated with rightwing tendencies.

For those who use it offensively (especially if they're dominant person and use it on the non-dominant as a way to insult them which can be walked back if 3rd parties take it badly), yeah I agree that it's commonly done by those with a kind of personality which is highly correlated with being a rightwinger.
