I find it more than a little ironic that you choose to paint others with a very broad brush while making the claim that those people paint others with a broad brush.
Personally, I try to treat others based on their individual actions. Perhaps you should try it sometime.
I didn't realize that whether people can or can't change was a political, left/right thing.
I'll assume you're asking that question in good faith, just somewhat awkwardly.
It depends on the person and the situation. Wouldn't you agree?
