I feel like I'm stepping around landmines replying this, but I never liked the analogy either. It works fine at a small scale, and I'm fine with that, but everyone here wants to apply it universally at a macro scale to the point it's just ridiculous.
e.g. If a nazi moves in down the street, and everyone else doesn't up and move, regardless of their financial situation, you live in a nazi neighborhood. Guess you and your kids should just go live in your car because...moral purity or something.
