Human Spell check: number one way to utterly destroy your opponent and make it known that you are a superior human being is to correct their spelling. Using "u" as a stand in for "you" is for simpletons, and it is your job as an intelligent human being to imitate your English teacher and reply with "*you". Doing this with any other words is sure to destroy that other persons argument and make yours better. Everyone knows that facts are for assholes! Grammar [url=http://www.wikipedia.org/wiki/Godwin%27s_law]-godwinslaw!-[/url]: want to make your opponent seem like a cretin? Simply reply to their thought out argument with a correction to their grammar! Did they use the wrong from of "your" or "there"? It is your time to shine. Swoop down on their mental error that could happen to anyone with an efficiency that only the Gestapo could admire. And gosh darn it everyone will think that you're so smart that you have the ability to nitpick and argument to find that one error. Honestly, you don't even have to include an argument to make someone's argument seem invalid! Do one or both of these things and you are guaranteed to win any online argument you come across.
