I suppose you could turn it round and ask: why are certain groups so obsessed with forcing immigration on people that don't want it? Don't those people have a right not to have their minds changed by people with an agenda? Who decides what opinions are palatable or otherwise, and why are they seeking to subvert commonly held beliefs for their own benefit?
I was thinking more the ideologues prevalent throughout virtually every major global institution and goverment. But there does seem to be evidence of NGOs and traffickers collaborating in the Mediterranean for example.
