I wonder if people realize posts like this only push away potential converts?

Even if Centrists were as good as this post makes them out to be (which sadly they're not), smugly asserting that everyone else is worse than you is a terrible method of persuasion.

Though I suppose the point is to feel morally and intellectually superior to people who would vote differently. Rather than to actually try to woo the most voters.

Edit: Fwiw, I believe the best option we have currently is to vote for the Democrats. I simply don't see an alternative option that is as likely to keep Trump out of the Whitehouse again. Though damage mitigation is not my favorite strategy to employ, in this case I believe it is the "strongest" play available.
