It's peoples home-life...thats where it all starts. It's not like this in ALL cases, but in the majority of cases...bullies for example...they're generally bullied at home by older/stronger people in their family...when people in their own family don't respect them do you think they'll have any respect for strangers? People with stable lives at home in the family do not act so outrageous in public...it's the ones with broken homes. Whenever I see douchebag likes this I can't help but feel sorry for them....because they've prob had massive issues in their families, like a dad that beats them up....or never had a dad around...or they were molested/bashed by their parents/uncles....thats how I see it lol. Or they're just people who hate life and just want to cause annoyance and pain for others so they drag people down to their own sad level. No worth-while human being acts that way...stay away from these people...just ignore them...and /pity at their life.
