Extremely perceptive. I have been where this man was, many times in my youth. I studied in a school that was mostly men, and consequently the situation was very much like his.
The man you describe does not hate women. He is angry at them. It is not the same thing. He is confounded, frustrated. Over time, his experiences will damage him unless he has some positive experiences to counteract them.
The piece accurately captures how shallow and snap judgmental people can be — both men and women — especially when they are young. There is a say, “Youth is wasted on the young”. It is very true. When one gets older, one can see one’s shallowness and correct it.
