I've found it to be pretty effective to simply not engage with those who keep taking the worst possible interpretations of your (or others) arguments. It sort of simulates an environment where everyone is charitable.
That's alright sometimes. But there's usually a 100 (or something) readers to 1 posters ratio. If none of the "trolls" are contested that leaves the impression that it's a legitimate opinion.

In other words, "Don't feed the trolls"
