Calling Islam an evil religion isn't calling Muslims themselves evil so there is no lumping everyone together. The one thing common to most religions is the belief that others are wrong. Remove religion for a second and lets sub-out politics. I believe liberal politics are appalling and wrong. Liberals think I'm wrong. It's part of the definition of our different views. I can't be a conservative AND a liberal at the same time. I still recognize their right to exist, but I'm going to discredit their beliefs every chance I get. That doesn't make me a bigot. It just makes me a person with strong beliefs. And vice versa.
Crummy example but I'm in a hurry. Sorry.
