I heard that a lot in school, yes, school is where we pick up all this rubbish. So basically, teen society told me that Southerners were incestuous gun-toating bible-humping rasists who vote only republican, blondes are slutty born-morons, redheads are untrustworthy bitches, cheerleaders & football players have a 90% chance of living the Bundy life (Married with Children) after college, all children of the poor class joined gangs & did drugs, all guys who don't have deep voices are gay, girls who wear boyish haircuts or wear plaid are gay, all goths believe they are vampires, nerds all die virgins, all women who have premarital sex are sluts but it's okey for men, & long hair on a man is the worst sin a man can commit.
This is the kind of bullshit I learned in school, & I don't believe a word of it.
