accusations of "extremism" are not critical arguments
Of course they are not. But such perceptions have consequences for those who are not hermits or safely ensconced in an ivory tower. If you want to persuade (and you do, don't you?) the common people, getting labeled as an extremist is not particularly helpful.
I don't attempt persuasion via attaining social status and trying to manage people's perceptions. I don't think that method can work for what I want to do.
