I'd say the ubiquity of negative opinions regarding high school is because this is a site dedicated to gamers.
I have no data to prove it, but I'm pretty sure there's a positive correlation between gamers and introversion.
And since socializing is a large part of high school life, introverts, and therefore gamers, and therefore most of the people on this site had a poor time in high school.
As a introverted gamer myself, I am part of this group. My social life in high school was primarily unsatisfying. However, I did manage to enjoy what few good social moments I had as well as plenty of stimulating academic classes.
