You can just dismiss the person if it makes it easier for you to comprehend. Alot of times those people are insecure because they were bullied, or beaten or because an authority figure told them they were worthless. And you're on the receiving end of that angst. Which is unfortunate, obviously you don't deserve it. But we need to build a new world. Our current world is divided.

Your attitude creates only enemies. In a divided world, the best path forward is solidarity. So sometimes that means forgiving someone their flaws.

I'm a Pakistani American Muslim. I've been subject to racism in airports and elsewhere. I've been called Al Quaeda in school. I've had guys tell girls I was dating that I was going to kidnap them. I have been subject to numerous "random" checks in airports. My fiance is a Hispanic Christian and some of her family told her they weren't going to attend our wedding just because they couldn't support her marrying me. I could have just dismissed these people as racist and forgotten about it. But instead I invited them over to my parents house for dinner. And they changed their tune and now they are planning to attend.

You wouldn't be wrong for dismissing people. But in order to build a better world, we need to try to connect with people. Sometimes it means forgiving people who wronged us.
