I used to believe also this but then I found out who Daryl Davis was and I the best way to beat hatred is the way he beat it. Even thought there might be psychopaths who are devoided of empathy but the percentage of people who have it is really low and knowing psychology you can also deal with them in a functional manner by teaching them that if they commit malice it will have a direct consequence. Violence always generate more violence and we as humanity have evolved and we can deal with these type of people please don’t think this will change anything.

What Daryl Davis does might work if you are talking about a very small group, but by the time it reaches percentage points of the population that method no longer works as the societal support structure grows from these vial ideologies, the weaker an approach based on societal influence. Eventually the only option left is violence as you have two opposing societies and can no longer pull “radicals” out of their hatred.

Just like with the Fascists of the early 20th century, the only option left was to expunge these hateful societies.
