Nice idea... Except that you've empowered (with money) so many of them, that they can now actively stand against any attempt to curtail their sowing of chaos. At this point, all hyperbole aside, the only way to extricate niggers from societies like Holland and the U. S., would be the institution of racial pogroms; which would proceed only after all-engulfing, domestic conflicts (if not civil wars), and would then likely be hampered by do-gooder interjection from outside.

To be quite honest, poisoning their water supplies and food would be about as an efficacious an approach as you could take, without being in utero stymied by the their (((handlers))).
