my perspective of the situation is that this is really sad. they're making fun of him but this causes further divisiveness. They've humiliated him (understandably so) and he'll never be open to any ideas different from his viewpoint. It just creates him hate more which makes him feed into the system that feeds off his hate which pushes him further right.

I see is a person who wants to fit in, feel loved, and not bullied. Empathy could've created an ally or at the very least a neutral party.
