Bigot

A person who disagrees with any part or aspect of the social innovations of the progressive movement.

This definition supersedes the Merriam-Webster definition: a person who is obstinately or intolerantly devoted to his or her own opinions and prejudices; especially : one who regards or treats the members of a group (as a racial or ethnic group) with hatred and intolerance.

The problem with the Merriam-Webster definition is that it is politically neutral and, perhaps even worse, largely coherent, and somewhat stable, thereby robbing future progressive leadership of the ability to move the boundaries of mandated social approval at their discretion.
