I would not go around telling people you are an anarchist.

an·ar·chy
noun
a state of disorder due to absence or nonrecognition of authority.

So when you describe yourself as an anarchist you are saying you do not recognize existing authority.

This is exactly the problem with the hateful part of Antifa and BLM because they don't recognize existing authority. They loot, attack police, destroy property, kill (5 police in Dallas), etc because they feel they are above current law. It's the violent extension of the SJW right now who also think they can control what others say or do because it must be acceptable to them.
