There's a joke in right-wing circles
Actually, there isn't. The right-wing have no idea what humour even is; They do know that human beings engage in it, so they try to do it themselves, but it's far too complicated for their simpleton world view, so it always falls flat.
The right-wing have never grasped the difference between 'insulting' and 'funny' - it's funny to make powerful and self-important people look ridiculous; But making out that people who are struggling, or who simply disagree with you, are ridiculous, isn't funny.
If they appear to both be the same thing, then that is a good indication that your brain doesn't process nuance well enough for you to be a comedian. As right-wing 'thinking' consists largely of riding roughshod over nuance, in favour of making out that everything is simple enough for idiots to grasp; and of disparaging people for their weaknesses, or for their mere holding of a different opinion, there can be no right-wing jokes.
Despite the apparently contradictory observation that the right-wing is itself a bad joke.
Go figure.
