It's fine if I hit nerves, so long as those whose nerves I hit take a moment to consider, even in passing, why those nerves twanged.

There is, ultimately, nothing "good" or "evil" about ascribing yourself to an identity. After all, we are human. And that's an identity. Being proud of what you've accomplished is great. Being proud of what people you support accomplish is great, too. But attributing hatred, fear, evil, or whathaveyou, to an outside group... Sometimes they really do intend harm. And sometimes they really are incompetent or weak. But it is rare for a group to be both. They need to check if their worldview is truly internally consistent, and many times it is not, and people don't like the feeling of that introspection: It is easier to fool someone, than to convince them they have been fooled.
