I agree, I am not a huge fan if some breeds of dogs, but I don't think that there are any that are just inherently evil or going to kill everyone they come across. Some people are just extremely ignorant.
I see it happen all the time at petsmart. People avoid certain dogs because of the breed. It's so dumb. You can tell if a dog is uncomfortable or is possibly going to be a biter or something like that because of their demeanor, not their breed. So dumb.
