I agree with everything you say, except that when the questioning (as vehemently as they like) turns into a shouting match, each side not allowing the other to finish speaking. This is what I am seeing on the news. One person starts yelling and a bunch of others start yelling as a 'follow up'. That is disorderly! In a town hall meeting, if you are given the floor (or mic) you should be heard, then allow an answer from your respresentation, not a yelling match to drown out an answer you don't agree with.
