Well, it’s not about writing an exact copy, it’s about voicing your own argument. My point is, virtually every time someone just links an article and acts as though that were an argument, it’s because he has no argument. Just like Huemer talks about in that lecture. Many people don’t know anything other than what they believe, and can’t explain why they believe it because they didn’t come to that conclusion through any use of rationality or reason. So when faced with opposition they will simply look for confirmation of their belief wherever they can find it, and then present it in place of an actual defense of their position.
If the guy actually had an understanding of his argument he could make it on his own and simply use the article to support it. Otherwise, you may as well just send him links. Sure he won’t read them, but it would save you time. (Of course you could also just move on to better soundingboards and save the time of just trading links).
You don’t have to explain marginal benefit. If you like it, that’s fine. That’s all you have to say. (Although you also admitted it pissed you off too.)
I understand this completely. Glad you see it that way.
