What they mean is...
  1. We live in a world of whiny babies and I'M going to fix it!
  2. I bet these people aren't aware of all their shortcomings and flaws. I can help!
  3. I'm brave and edgy. HATERZ.
  4. Just because it hurts people around me doesn't mean I should censor myself.
  5. I have freedom of speech. Tact is basically burning the flag (the US one).
  6. I'm a douche bag.
