NOT ONE of the speakers is on our side, so it's IMPERATIVE that we flood the audience with sane opposition.
One of the best ways to counter them is to simply STARE at the speaker. DON'T REACT. They will be trying to provoke us into matching their prejudices about what gun owners are like.
If we don't react, but instead look at them as if they are exhibits in a zoo, THEY will be the ones who become defensive.

The time to counter what they say is afterward, during the public comment portion of the dog-and-pony show.
See you there.
