There are two paths to convincing people.
One is a rational path and the other is an emotional path.
One problem with some of the gun rights advocates is that they think the emotional exemplified by Yeager or Ventura will overcome the emotional path reaction that occurs in many after Sandy Hook.
A rational path analysis of why we should have guns may work on some capable of analysis. The emotional won't.
Some are already convinced of gun rights so listening to a Yeager or Ventura appeals to them emotionally.
That is not going to work with many.
