Bill Hamblin asks an excellent question:

The answer, of course, is twofold: First of all, some people are on the right side, the side of love and kindness, while others . . . well, they’re emissaries of fear, hatred, and obscurantism. Second — and this is essentially the same answer as the first — some people are good and kind, while others are evil.
The choice is pretty easy, once the facts are understood. For the sake of the children.
