My complaint:
I have been a loyal viewer of nbc for 70 years and that is about to change. For you to give this candidate broadcast time is an affront to all of your viewers. Maybe you should watch msnbc for 24 hours to see how reprehensible this person is! This town hall only promotes his pile spewing. This next election is going to be the most important in my life time and to have the network that I spent most of my life favoring giving him an audience makes my stomach hurt. Please come to your senses and cancel this town hall for all our sakes.
Suggested solution:
Cancel town hall
