Hostility is orthogonal to truthfulness.

Here's a hostile but true statement. A teacher asks, "what is 7 times 8". A student replies, "54." The teacher says: "Oh fifty FOUR, oh SURE. That is...WRONG, WRONG, WRONG, WRONG. My THREE YEAR OLD knows that it's fifty-six."

This is extremely hostile. But it's 100% true. (At least if the teacher has a three-year old who knows 7*8=56; I've known three year olds who did, so it's not impossible.)

Are you sure you don't actually understand that "pointless" is a negatively-charged ascription of value and you could have made the same point in a less hostile way? That accusing someone (or at least appearing to accuse someone) of supporting highly dehumanizing phrasings applied to women is an attack on their moral character and humanity while an equally true but neutrally-phrased characterization is not? And so on.

(The extremism part is a bit more complicated but also you can state a true example while also maintaining an extremist attitude. For instance, black-and-white thinking and/or statements about an issue with gradations is (literally) extremist. Most of the statements I charge are extremist are extreme for this reason.)

Anyway, because the reply is based on a misconception of the relationship between hostility and truthfulness, I shan't go on.
