Magmarock: Yeah I know we all agree, that's why I'm asking for help at batter presenting the argument. I know it's kind of petty, but I really think DRM is dangerous to the industry, and piracy might get the blame for what DRM causes.
Something you need to understand is that it simply isn't worth having a discussion with some people. Ideologues, sophists, zealots, etc- there's nothing worthwhile that can come out of a discussion with such people. You're not going to convince them of anything- the stronger the argument you present, the shriller their protestations will become. But more importantly, their counterarguments won't contain anything of benefit to you. That's the important thing to recognize- a big reason to have discussions with others is to expose yourself to perspectives that you may not have considered, to improve yourself and your own views on things. If neither person in a discussion is able or willing to benefit in such a way then the discussion is a complete waste of time.
Ultimately you have to be able to recognize when you are no longer dealing with a rational person, and then just write them off. Ignore them, work around them, if necessary remove them from being a problem; but trying to reason or argue with such people is utterly pointless. Life is too short to waste time on that.
