Let's go over the term "TERF" and why it's an offensive term.

I don't care if it's an offensive term but I do care that it's being used inaccurately.

Women who simply don't want men in their locker rooms or bathrooms are being labeled "TERF" when they are not necessarily radical nor feminist.

The only time this term applies is when the person 1) is an actual radical feminist (e.g. reads Bell Hooks or wears pussy hats or does performance art with tampons, you know the type) and 2) thinks trans women are not women and excludes them from their feminism. Only then is the term "TERF" appropriate.
