Are all middle-aged fucking insane?

Teachers at my school that are middle aged women constantly comment about my brothers hair and how it looks (hes trying to grow dreadlocks.)

They get mad at the pettiest of things. Examples:

A friend of mine didn't know what songs we were gonna play at a concert tomorrow so he kindly asked the teacher. She started yelling at him in front of class and claimed that he has alzheimers or some shit.

We had a concert to play at 10:30 and another one at 13:30. I asked if we would move the equipment to the sides of the theater (since i didn't know if someone else was gonna use it during the off time.) She started yelling at me and calling me stupid. Same teacher btw.

Not a single male teacher has ever done anything like this, and most of them are around the same age.

My mom is turning 50 this year. Every time we have a fight (which usually starts from me not "remembering" something she has never told me, or me asking for money when i haven't got any in 2 weeks.) she calls me things like "worthless", "scum" and has even slapped me and has grabbed me and slapped me a few times.

Also when she said she has no money she went on and bought a new car because that's extremely logical :).

My dad never calls me these things and usually explains everything with logic and even tells my mom to shut the fuck up and calm down.

Getting to know TRP and MGTOW at 15 is really an eye-opening experience and probably help me alot if things get more gynocentric where i live.
