When everyone starts avoiding answering challenges to their opinion we end up in a highly divided society, where there is no understanding for the other points of view and no common ground. I think this is visible already in our world. There's a fine blurry line between challenges that address essential aspects of an idea and those that divert attention to minute details or go on tangents. I would say the ideal attitude would be to try and answer a couple of such "attacks" or explaining why they are besides the point.
