Right, but the problem there still comes down to the preciseness of the language.

"Anti-trans activist" is vague enough to refer to both JK Rowling and Ben Shapiro, despite their angle, impact, intent, and target audience being very different.

As an umbrella term that certainly works as a catch-all to transphobes with an activism or information-driven platform, but TERF still identifies a specific type of anti-trans activism that is worth having the language to identify
