>I think you're smearing missionaries a bit - they haven't ALL engaged in forcible conversion of natives. Quite often it is a voluntary decision.

I would disagree on this point, Sure not all were "forced." There are invisible points that cause native nations to collapse. The missionaries didn't have to force them to come, there presence alone had enough effect on the region to force them to move to the missions.
