Praxis against neofascism
Quite honestly, if you're talking to a nazi or a fascist, punch them, or verbally beat them down until the fascist noises stop.
The Daryl Davis method only worked back then when all of these bedsheet-wearing scumbags were ballsy enough to be out in the open about their racism. Nowadays, they're smart enough to hide their power levels behind formalities and civilities, and will play every dirty trick to socially punish you for even trying to size them up.
Give them no quarter.
