I know exactly what you mean. I do the same on public forums, say with pro-Brexit types. I pick the sort of person who makes the sort of comment where I can tell there’s a lot of batshit bubbling under the surface, and I just take their comment apart, systematically, and then their responses get wilder and wilder until they expose just how racist, stupid and crazy they are. It often ends with them going “I don’t know why you’re bothering - you won’t change my mind!” but of course, it’s not their mind I’m trying to change - I’m just trying to expose the hatred, stupidity, and simmering violence to the more moderate people they know.
It didn’t work in the case of Brexit - well, it did work in several instances, but there weren’t enough of me.
