"I don't know how one gets trained to think that way, but I can make a few...educated...guesses."

Well, I don't know what your guesses might be, but I can tell you the process.

First, one believes in a rule of law. Most of the time, anyway, and all of the time when the matter isn't urgent.

Second, you wonder a bit what you might think if, say, China had Predators around the world, and was killing people they didn't like. Maybe took a shot at a carload of 'em outside San Diego.

I wouldn't like that. I wouldn't like their doing it at all, killing at will, I wouldn't want 'em sneaking into my territory.

So, between believing laws are the preferable way to relate with each other, and not believing in ANYONE having the ability to kill anyone they choose without following the laws, one winds up liberal.
