Stupid People
I don't mind stupid people. They do stupid things and, yes, sometimes what they do can be quite hurtful to other people. Whenever that happens, you just have to ignore the whole situation. After all, they're stupid. They know not what they do.
I do mind people who are not stupid but pretend to be stupid. Sometimes they do things that they know will be hurtful, but they act like had no idea that anyone could possibly be offended. "Huh?" they say. "Huh, I had no idea ..."
Of course they had an idea. Just another spoke in their malicious, insecure wheel.
To them, I simply say, "Pfffffffttttttttt ..."
