In argumentation nothing beats common sense and white-hot Truth.
If I want to convince you, specifically, in debate, that is what I would use.
But bear in mind, you have people who think the answer to a mass murderer killing children is to establish a gun free zone around a school, and make the penalty a misdemeanor. How much do you think logic and white hot truth will affect those idiots? Liberals think differently. fMRI’s show their brains are lighting up differently. Psychological tests show different cognitive characteristics. Even MRIs of their brains show structural differences.
I suspect that the difference between us is, I ran into a gross defective, and saw just how differently another person can think. It can almost be like they are a different species, detached from logic. Once that happens, all the logic and white hot truth won’t do a thing. You need to know what hurts them, and how to apply it.
Just out of curiosity, do you have a really smart sibling?
