Joel reads your post looking for key phrases that stand out as you not agreeing with him or missing some negligible point. Then he decides that you're against him or stupid. Next step, is deciding which argument against him he wants to argue against. Then he assures you that you made said argument and then he starts attacking the point. Lastly, he goes through and adds a bunch of filler, sometimes having nothing to do with anything said or perceived in weeks. Then he hits submit.
