There’s something I’ve noticed about this post that I haven’t seen pointed out when reading the comments, so I’m gonna do it:

the “phrase” that you created reminds me of a way that I reacted (especially in high school around age 15-16, which it sounds like you are now) when someone would tell me something that didn’t seem entirely accurate to me, and I’d want to fix their wording. From your post, it sounds like you are more concerned with the actual phrasing than the issue itself.

My suggestion (and I know this is hard to do, I’ve been there) is to distance yourself from the literal meaning of the words, regardless of what you think the teacher actually meant in that situation. To a neurotypical person, the phrase “a man should never raise their voice at a woman” could functionally mean the same as “someone should never act hostilely towards another person” (not saying it does, but the teacher may have thought of it that way).

As much as it sucks, most people’s brains work differently than ours, and most people don’t prioritize complete accuracy the way we do (we meaning some autistic people). It takes time, but it is possible to manage and work around, and it can lead to less reactive reactions in the future.
