No, originally the term was used unironically, largely for deviations from Marxist theory.
Laura Miller

You’re right (and I was wrong) that originally the term was used unironically, but the usage in The Black Woman: An Anthology (1970), “a man cannot be politically correct and a [male] chauvinist, too” seems more to do with “identity politics” than with Marxism or excessive orthodoxy. If it was about left political theory, then it was wrong, since there was an awful lot of male chauvinism among leftist political theorists. Of course, feminism was instrumental in changing left political theory so as to make the statement true by elaborating the rights of women and tying them to left objectives, and to make male chauvinism unacceptable in left groups. (Unfortunately, the demonization of Hillary Clinton has created a path for its re-entrance.)
