What's 'doing a Beth'?!?!

Sorry, nothing bad. Just willing to argue with a bloke who knows very little about the subject he's arguing about. I myself cannot begin to debate Chinese with a person who only knows disjointed random chunks of Mandarin gleaned from Wikiturnoi which always amounts to him getting the wrong end of the stick. The problem for me is no other poster it seems will know whether he is right or wrong; and because he's brainwashed them into believing he's an expert(by repeating it enough so it becomes an intrusive though) they could well believe I'm the idiot he says I am. Hahaha¬! Alarmingly you could have the same problem, to a lesser extent, with your good ESL and grammar knowledge.
