We are told on Sundays that we should love our neighbors as ourselves. On the other six days of the week, we are exhorted to hate. ... It might be objected that it is right to hate those who do harm. I do not think so. If you hate them, it is only too likely that you will become equally harmful; and it is very unlikely that you will induce them to abandon their evil ways. Hatred of evil is itself a kind of bondage to evil. The way out is through understanding, not through hate.
