MGM. "self-satisfied self-righteous lefty wankers...!"

Do please tell. Are those of the opposite political persuasion "self-satisfied self-righteous right handed wankers..."?

I raise the point entirely out of curiosity as to whether this is the self satisfied, self abusing MtheGM we know of old, whether he is of the right handed persuasion, and whether he is liable to change hands when he learns how to count up to 99?
