Assivist 

The complete opposite of a passivist. Not only does an assivist believe in confrontation, but see it as a way of life. Often, assivists employ cruel sarcasm as a means to belittle and exploit an opposing party. In many instances this is for the sole purpose of gaining recognition and the need to inforce opinions onto others.

Jared wouldn't stop making fun of me for the way I eat my food. He's such an assivist.
