Did you know that there is a really simple way to always win arguments on the Internet? Really it is very simple. I can explain how to do it in one sentence. Declare yourself the winner and don't read any responses.
If you have lots of time there are some variations on this simple tactic.
One is to write a really, really, really, really long post with little or no formatting. This will make it difficult to read. If someone responds to one of the points in your post but not to all of them counter by speaking only to the point they didn't address. Ignore anything else they said.
Another useful variation is to refer so vaguely to those you are "arguing against" that any response to your statement can be parried by saying "that wasn't the person/point I was writing about."
There you have it. You will never lose an argument again.
