Ah, the dreamy musings of a serious social engineer. . . . .
Ostracizing a fundamental human choice, then another, and another. Just can't teach humans without these displays of hate, huh? Maybe sometimes you have to fight fire with fire, when you can't raise the level of discussion to an abstract ideal, oh, say like religions sometimes do.
Let's take the whole "Whites Only" sort of business that used to thrive on the commonplace ignorance and fear. A lot of businesses feared that whites would ostracize them if they did let the "different" folks in. Nobody had the courage to break with the establishment in place. So of course you had to have northern liberals and Republicans pass federal laws and send in the federal jackbooted troops. You couldn't win this one by discussing American ideals, right? If it was only the jackbooted cops/soldiers who could secure inviolate human rights, why did Martin Luther King gain impressive audiences?
The blacks did not have it as bad as another "minority" I can think of. The blacks were obviously valuable workers, with no way to escape, and sometimes they were kept alive. The indians were "savages" that just needed to be killed. Even Abraham Lincoln just thought they should all be killed. We raised armies to do that, and when they couldn't just finish the job, we gave them pitiful little reservations and posted soldiers nearby to make sure they couldn't roam out to hunt. Some of the plains indians were so troublesome we had to have US Grant and our Congress give out free guns and ammo, and free rides on trains across the plains with the express mandate to wipe out the buffalo herds.
This to people who had lived and traded with the trappers for decades.
Government force is always the preferred tool of progressives, right.
