So, did Kelly advocate for gun bans of any sort in his keynote speech? Did he say anything nasty about guns, gun owners, or even gun manufacturers? Even in highly vieled "code"-speak?
He happens to also be a former astronaut and could have been talking about the former greatness of the country's space program, or the need/desire to move NASA back from the brink of being the official Muslim Religion of Peace cheerleader towards their original mission of showing those evil commies that we can do it better.
I don't know - I wasn't there, have read nothing in the 2A press about his appearance, and actually have almost zero interest in looking it up in the innertubes.
That he might use his "honorarium" to further his/Gabbie's agenda of gun banning is IMHO to push the Farm Bureau too far into the "protect gun rights at all costs in all activities" box. Unless he was being paid to talk up gun bans and other "reasonable" restrictions.
