...we have government services now that we didn't have during our great periods of immigration. Those who came here then came to work, not to suck off the teats of the nation at best, or defraud the nation of billions at worst. And if they failed, they got help from their local communities and churches, not as government entitlements, and not by defrauding the government.
You can't make your government benefits available to everyone in the world, in their languages, register them to vote when they get drivers licenses...you can't do all that without destroying the country. Destruction is the goal, though, as the plan is to rebuild like 1919 Russia.
Evil preaches tolerance until it is dominant, then it tries to silence good.
