Shooter incident at elementary school in Uvalde, Texas - 19 children and 2 adults dead

Sure, but that's not what he said. If this is what he was getting at, then I don't really disagree with your sentiment. Several gun owners on this and other threads have talked about what they can do to change the situation, from training, to licensing, to registration etc. Now getting support for those things at a state and national level is a different challenge, but it can be done.
The problem is that Semper and others like him who are all for responsible gun ownership seem to be in the minority. We have legislators posting Christmas cards of them and their families all holding guns. The sentiment among many gun owners seems to be tha the second amendment is the most important amendment, and trumps all other rights.

This is what I get out of all the headlines of massacres committed by nuts with AR-15's, and the complete lack of response and outrage from many legislators.--"Gun rights first, **** everything else, including the rights to Life, Liberty, and the Pursuit of Happiness."

I will also admit my jaded bitter cynicism regarding the US is at an all-time high right now.
