I've seen the term "benovolent sexism" used for gender roles that are, in theory, complimentary, but in reality are bad for society. e.g. "women are good with children" is in theory a compliment. But in reality it means men who try to work in child care are viewed suspiciously, and women are expected to give up their careers to look after children (because they are better at it!). Benovolent sexism (and hostile sexism (like "women are too emotional to wield power")) are bad.

Likewise, "benovolent racism" is bad.
