"So if they want to kill all the Jews, what's the problem? It's their country and they can do whatever they want with it."

Creating laws based on popularity makes populism rule. Hence why democracy usually has an explicit legislative branch abstracting over individual sentiments. That helps prevent policy from being devised through an overly greedy algorithm.

That is not to say it prevents all these problems. But it evidently helps.

Well, the difference is that you're within your rights when you vote on whom to admit to your house/town/country. You're not within your rights to round up people already there and gas them. Let's not compare the two.

The parent comments are talking about direct democracy and its tendencies in Switzerland. Not specific policies (for you see, such extremes haven't come up for voting there lately). Perfectly comparable.
