People who complain about stupid problems. I.E. "Dude, I frickin' hate when people flood my news feed on Facebook with stupid stuff," Mother fucker, are you aware that some people have real fucking problems. Also anyone who has ever posted on a "First World Problems" people like that probably don't deserve to live.

People on either side of the smoking debate who are way too zealous. Anti-smokers, its a choice, if you don't like it move 6 feet away from the smoker and you will find the air to be clean.
