Why indeed. I feel that the TRAs use a lot of very confusing language and rhetoric to conceal the core idealogical and politic goals they're going for, because if they asked outright, using ordinary lanugage, a lot of people would say 'no'. So everything needs to be couched in careful terms and phrases that borrow from popular social justice movements. They frame agreement as the morally progressive thing, frame all disagreement as hate speech, and generally shift ideas and words around so that people who feel uneasy find it difficult to articulate why. And people who aren't that invested just look at the slogans, think they sound nice, and agree, not looking into the deeper ideological position that those slogans express. Then the attitudes out sheer outrage and hurt also provide a guideline as to how bystanders should react. How many people have you heard say "oh, she's a T*RF!" without even knowing what it means? Clarity can only help us.
