It would be an extreme position in most of the United States history to completely honor the treaties with the American Indian tribes and not ethnically clense the population, but in my humble optinion that extreme position would have been a better outcome.

It was an extreme position for John Brown to do what he saw was right for the society he was in, but he was certainly right to liberate the slaves.

Can there be positions where compromise is necessary? Sure when material limitations show up.

Compromising with entities that can't justify their existence like the bourgeoisie are decisions where one of the more "extreme" options is the right one.
