They also want to move the general demographic toward something they can more easily control (third world culture).
That is true; they want a population that has no history involving the Magna Carta, Bill of Rights, etc. - as Steve Bannon so eloquently put it: “This new barbarity that’s starting, that will completely eradicate everything that we’ve been bequeathed over the last 2,000, 2,500 years”
This is the point where I laugh in their faces. They think they will be in charge and in control of these third-worlders? That's a crock. The third-worlders would brush them off as an annoyance and continue to do as they please. If the mighty SJWs attempt to interfere further, they'll disappear.
