Honestly, I don't mind howlers. I just suck it up and ignore it. If they continue, and I eventually loose it, I just go somewhere else. I never argue with them, and the howling is quiet (at least to me). Seriously, most people need to just not explode with rage when there is a Howler/Roarer. All of those solutions are good ones, and I am glad you made this rant, because the people who complain really need to see this.
