I had a similar problem with SOPA. I had lots of people telling me SOPA sucked, but very few were willing to tell me why it sucked. It seemed the bill was just a product of evil and I should oppose it. There was a lot more seeking to be understood than to understand. (Caveat: I wasn't really reading HN at the time, where maybe I could have gotten a decent discussion, including opponents to the bill who could have described why the proponents liked it without dumb sarcastic comments.)
