"In view of the reality that the most major threat to the survival of the planet is runaway human migration, maybe the BNP is just what the world needs." Rig

Rig, surely you mean 'population', not 'migration'?   Even if you were able to keep all immigration out of the US and other developed countries, that would not cure the planet's ills.

I simply fail to see why a human being born in one part of the world has less right to survive than a human being born in another part.

By the way, I think your remark is deplorable.
