I prefer deriding them or forceful admonishment to the point of causing ideations or the feeling of intense stupidity. The key to doing it effectively is sharply attacking the weakness in their logic or thought process. I especially like this as a strategy when people are citing consensus or making other weak arguments with extreme arrogance. It is risky though since if you aren't correct it will make you look like an idiot and asshole instead. I think oftentimes kindness (especially fake kindness out of politeness) is actually cruelty. Making a well functioning society requires adversarial confrontation for bad ideas and behavior.

I look forward to checking out Jacob Rees-Mogg now. Thanks for the mention.
