Please understand, I hate to give these Progressive Anti's anything! But I do believe that criminals and severely mentally ill people should not be able to acquire firearms from legal sellers. Arguing otherwise, plays into the Anti's hands as it allows us to be painted into the "gun nut" narrative unfolding before us.
If just half of the 80+ million gun owners in this country stood their ground and said NO! like they meant it, and voted likewise, there would be no mention of gun control. Instead we have 70+ milillion of them worrying about being called "gun nuts" and doling out my cake a slice at a time, so as to appear "reasonable".
