Part of the problem is that people think a position such as feminism is political, but being sexist (i.e. opposed to feminism) is not political and therefore allowable.
Just as with *racism*, I think we as political people need to frame / contextualize *sexism* as being an *institutional* thing, primarily, as with the lack of legislation that defines abortion as health care.
For racism, it's *redlining*, environmental racism, police brutality / killer cops, and so on.
(See 'movements / institutions', about halfway up in the following diagram.)
