My answer to when? is;
Not Now and not Never. I have not been able to narrow it down much more than that yet!
Just make sure the abuse is warranted, Did you understand that I meant that I am not there yet but that it it does seem likely that we will end up moving from political protest to a "more aggressive posture" at some point. I am watching but unwilling to provide the asshole opposition with specific details.
I believe that the lesson of the Warsaw ghetto is that you cannot let them take your firearms away or you are lost. The recognition that threat levels had reached a new high after 9/11 was one a big reason for me to return to shooting after 30 years away and teach my son. (Beside that it has been fun.)
One of the lessons that I had to learn when I took on my corporate security role 15 years ago was to be clear about my scope of responsibility. I am charged with keeping our employees safe not with "putting criminals away". If I can get the threat out of my workplace with a minimum of impact and minimal emotional attachment to my company then I have succeeded. If that includes putting a scary bastard away by assisting the police that is gravy, Not My Job.
My kids safety is my job, then mine, then friends and family within reason. I am prepared to do what it takes for that mission. While I am prepared to give my life for the ideals of the constitution which I consider the single greatest human achievement outside of science, that does not mean I will throw it away for the sheeple.
I do not believe there are enough folks left in the country who even understand the constitution to save the whole nation at this point. that is why I suspect that those of us with a clue will eventually congregate in regions that we can defend politically as well as physically. NY and CA are in my opinion lost causes without some dramatic significant emotional event that changes the sheeple's behavior.
At this point in time, I decline to expend my life attempting to be the catalyst for that event. They will just change the channel.
Highest regards for the grit to grapple with reality.
