Breedism is to judge a dog based on its breed and not on it's own history, behavior, or personality. Breedism is equal to racism, just people to animals and not people to people. Breed Specific Legislation (BSL) is a form of Breedism in our own Government.
Breedism is to look upon a dog and say it is dangerous because of what it is. Until you actually see it be dangerous or aggressive is to judge without right. Same as saying because someone is of a certain race they fall into a specific category. Such as they are illegal, lazy, stupid, or dangerous because of their race and not who they are.
