Maybe they could take a new name, and go a long ways to *specifically* exclude more radical feminists?

There's no real way to police people's ideologies without sounding like a totalitarian. There will always be extremists and radicals that make the most noise within any political movement. You can't really distance yourself from them either (some crazies will always follow because they always believe themselves to be moderates).
Besides, all the good words are taken. Womanism is feminism with a WoC focus, humanism is a morality system and egalitarianism calls communism to mind.1
