What I'm trying to say is that, as much as that may make us feel superior, we don't need to win arguments and, let alone having fascists recognize we are right, we don't even need to be right in the first place.
I'll give you a (surreal, thought-experiment-like) example:
Would a blanket amnesty for all of Netanyahu's crimes be "right"? Should we support it, if it meant stopping the massacre?
