Nope, sorry, I'm right. There is no 'wrong' way to use a comma, only 'non-standard' forms. Where one person may feel a comma is perfectly justified, another may decide it doesn't fit at all. When it comes to editing the use of commas, there are many instances where it must be included in order for the sentence to make sense to the reader. The main use for a comma is to create a pause. This can often be a dramatic pause, for example in the course of fictional discourse or during a speech given to build up emphasis before a noun or pronouns, usually it adds a condemning tone.

I really think you should quit while you're ahead because I have reems of sources and information to back myself up here.

Everything that you just said is shit. Every word of it. Show your proof, and I will concede the point.
