I need to learn to accept that someone will always disagree with me. No people ever agree on everything.
Tolerance is the word greatly overused. Curiosity is a better term. It is good to stay curious about others. But do not get cozy with things you consider evil.
In the heat of the moment the differences may seem to be unbreachable but time might change that. Good people disagree, sometimes bitterly. Even smart people do silly mistakes, of course I am not smart and I do a lot of them. It is difficult to learn to live with this knowledge, but it is necessary.
