Everybody you don't agree with is "close-minded". It's the fact that they can't seem to see the sense in your own position that makes them seem like such benighted fools. But they look at you in the same way. Unless you can accept that _to those people_ opposition to vaccines or whatever _does_ make a kind of sense, then I suggest you're being equally close-minded. You may be right, but your mind is not open to the sense in other people's worldviews.

The division of our society into ideological camps that point fingers at each other and can't see the others as basically-sensible human beings drives me crazy.
