About a decade ago I had started down the manosphere/incel path as a very lonely individual. The only reason I stopped and kinda 180'd outta that was because the ideas I was listening to were being made fun of and insulted by most of the internet. That was the influence I needed to do some self-reflection.

Point being if you don't insult the person but you make them think twice about the ideas they're accepting, that can be effective.
