> It's not 1800s, if the given population doesn't like missionaries, as far as I'm aware it's equally free not to listen to them. Or to throw them out.

The given population doesn't know that though...

That argument would necessitate treating them like children rather than adults who can think and choose for themselves. I don't think this is a healthy approach that would work out well at all.

Know what? They don't know that they can not listen to people? I don't believe that at all.

You claim they think they have to listen to missionaries?
