I remember getting the shit beat out of me by the neighborhood bully, along with my sister and a few friends of ours. He used to throw raw eggs at us, ride by on his bike and kick us while we were walking home from school, etc.
I don't know if he learned it from home. I do know that it stopped when my mom tore his ass off his bike and dragged him home to his own mother.
It's a little worse because of social media - kids can't escape because they are harrassed online as well (my own opinion on that aside).
Mostly it's worse because we are so self centered and unable ot let anything roll off our shoulders or take responsibility for anything. It used to be that kids handled bullies, or if they couldn't, parents and schools did. Now kids cry to their parents and those parents cry to the schools, who can't do anything for fear of being sued by the bully's parents.
I remember bullies in school, but nothing like what they do now! A kid told my son he was getting his dads gun and killing our whole family, one kid down the street screams things up the street at out son, flips us all off, called me a bitch, threatened my son with a knife. I tried talking to his mother, she claims her son "would NEVER!!"
The term is OVERused and MISused on a daily basis, which is why it seems like it's increased. Too many helimommies cry bullying when their little snowflake isn't particulary liked. Every childhood disagreement is NOT bullying.
I don't think there are more or fewer bullies now. But luckily kids are being educated that it is not okay to be bullied. I was bullied mercilessly in 7th and 8th grade, to the point of being suicidal, but there wasn't anyone to tell at the time.
