I have a couple of examples. I remember my math teacher telling a 5th grade class how all men are the same but women are all unique. The other one, which still bothers me to this day, happened freshman year of high school. I was walking to my locker after school and i noticed two of my friends stayed after class to talk to the English teacher. I was curious so i walked in and said hello. Apparently the teacher was telling two 15 year old girls that men need sex all the time. I stood there listening as she said "if there are no women around, then they will do it with another man, if not then they will find sheep or some other animal." I just said "I don't think that's true." I wish i told her to shut the fuck up instead, but i didn't consider myself a man yet. I didn't have any good male role models to bring to school either.
