Daryl Davis doesn't scale. Everybody likes to point at him but there is a reason why he is a unique case. Especially since it would be trivial for fascists to monopolize his time by just claiming to be open to discussion while actually not being interested in changing their views. This is why Davis holds his conversations in private. When done in public, his approach is exploitable to create a seemingly legitimate channel to spread fascist propaganda.
Well...

I've had interesting discussions about whether or not people like me should be allowed to vote or breed and whether people like me not existing would make the world a more peaceful place.
