Ableism can be intentional or unintentional. People can be ableist (prejudiced towards disabled people) unintentionally because ableism is so common that people may not notice that it exists. A person who holds such a prejudice is called an "ablecentrist". Some people say that ableism is a form of oppression. Not everyone who talks about ableism agrees about what things are ableist. Disabled people can be ableist, to other disabled people or to themselves, which is called internalized ableism. Some people deny that ableism exists.
