Many years ago, Stephen King wrote, "Calling 'Plan 9 From Outerspace' the worst movie ever made is like making fun of a retarded child." (He wrote that some years before the word retarded was replaced by more medically accurate terms, so we will cut him some slack, here.)
I think of that quotation every time I see some aggressively ignorant right-winger, like this one, avoid the opportunity to explain their position.
It's funny and easy to make fun of. But, ultimately, it is sad and makes anyone with a conscience feel bad for laughing.
