Well, sure. OrganicAnt, for example, will steer any discussion towards "meat is murder" within 500 words and then steadfastly refuse to acknowledge or entertain any other aspect of the discussion (even if it's about Smash Bros). One can safely ignore anything and everything he has to say even if you agree that meat is murder for the simple reason he's adding nothing to the discussion. HOWEVER you need to listen to him enough to appreciate he's got fuckall to say before you can go about your business ignoring him (like I did about four months ago). It's like the first time you get a new HD tuner. You need to flip through the channels at least once to determine which ones show old TV shows you like and which ones are nothing but the Home Shopping Network overdubbed in Korean.
