The piece of the puzzle you're missing is the fact that the electorate is not the supreme law of the land in this country, the constitution is. The constitution defines what the government (i.e. the people, via their elected representatives) may and may not do.
You seem to think that whatever the voters want is A-OK, that the very act of voting for something makes it legit. Well, no. Hell no! There are some things you can't vote into law. Quite a lot of things, thankfully.
The constitution is the difference between real liberty and those two wolves and the lamb voting on dinner. It's a darned good thing, given that we're all the lamb at one time or another.
The constitution is the biggest impediment to statism we have. I assume that's why people of your political stripes always seem eager to ignore it, or dance around its limitations, or redefine it into meaninglessness.
The constitution is why we can't vote for inherently evil things like slavery. That's one of the reason I wanted to get you on record as being against slavery. The fact that you couldn't bring yourself to condemn slavery as evil makes me wonder about your true intentions.
But if you can't condemn slavery, howsabout murder? Should the electorate be allowed to vote on murdering certain segments of the population (perhaps, say, people who post on internet message boards under names beginning with 'm')? Would such an act by the electorate be inherently evil?
If you can answer that question honestly, and then reason through all of the implications, then you'll understand why none of us here can tolerate socialism or any other form of tyranny or oppression.
