Presumably the same way saying you're a "women's rights activist" makes you fighting for a good cause and saying you're a "men's rights activist" makes you a sexist, and saying "black lives matter" is fighting for a good cause, but saying "white lives matter" makes you a Nazi.

The language is preloaded with a lot of existing conceptions about the state of the world currently, and the sort of people who use each set of terms.
