The far-left and far-right agree on many things. For example, to justify affirmative action, you first need to tacitly acknowledge that groups have differences and that there aren't other means to racial, gender, sexual proclivity, or hair color equality. The big disagreements are about the need for a "solution", and what a "solution" might be. They both have many members who seem to be okay with authoritarian attitudes, they both have many collectivists. Only one, however, can meme.
