This one is mine. I've found that I just cannot believe that certain things still happen in the 1990's with the rapidity of dissemination of information in our culture. Whenever I run across something that blows me away, I will add it to this list. People still litter. People still teach their kids to hate groups of people based on ethnicity or personal beliefs.
People drive with their dogs in the back of their trucks.
People advocate censorship. People think violence of any sort actually solves problems. People encourage limiting gender-roles in children. People still drink and drive.
