People who post questions that could have been Googled, then get angry when you answer with results from Google.
People who post a question just to get validation then get angry when your answer or opinion is not what they want to hear. Don't want a different opinion, don't ask the question!
People who keep beating out the same opinion in the face of facts which show it invalid.
Elitists who insist only the most expensive brands are adequate. Expensive isn't necessarily good - get over yourself.
People who keep posting the same old pictures of a Swedish 96 Mauser that was blown up by a heavy charge of pistol powder as proof Small Ring actions are unsafe. Check the facts before you post a picture dudes.
People who respond to a question with "I never had a..." or "I have no experience with..." Uh, then why are you wasting the OP's time?
People who post their hatred of religion and/or attack religion and those who practice one. Is this America or Mao's China? Don't like religion, don't read the posts. Yes, you are the problem - the religious person isn't hurting you, but you are trying to hurt them. And that is not American.
