You cannot logic someone out of a position that they didn't use logic to get to.
Only two options really, play on their emotional reasoning to make them feel the victim of their own beliefs, or you know, make their physical safety in question.
Manipulate them basically. Essentially weaponize the shift that conservatives have when they are personally affected by something. Think McCain turning around on gay marriage because his kid was gay or whatever.
If trump and maga can manipulate using emotion because these people only use emotional reasoning, surely a competent person can weaponize other grievances in the opposite direction.
Just make them more mad about something else that we can all agree on.
