I've seldom seen anyone who responded to a disagreement with "Why are you against asking questions?" who was truly just asking questions... except perhaps of the "When did you stop beating your wife?" style of question.

To use an example not likely to raise hackles on DU, take climate change deniers as an example. When one of them asks something like, "If the earth is getting hotter, how do you explain snow falling on the pyramids in Egypt!?" (this did happen a couple of weeks ago), you could try to explain how climate change leads to wilder weather conditions, not just uniformly more heat everywhere, but you know damned well that person isn't going to listen to you. Their question is a rhetorical question, delivered with the smug assumption that you don't, and can't possibly, have a good answer -- certainly not an answer that's going to be good enough to satisfy them.

These people are pretty much always stating conclusions, and their passion belies any pretense that they're really reserving much doubt that they could be barking up the wrong tree.
