I had missed this post and had to back my way over here after reading you had flagged, I know how patient you are with folks so I knew I had to read this in it's entirety, meaning the comments.
You are spot on, as I have said plenty of times, we are sowing the seeds of what has been planted here in the USA. When the government no longer values life, neither will the people (Rowe vs, Wade). That is how you end up down the road we are on, it is just a long and winding road that is starting to get more traffic (school shooters).
The first school shooting was in the 1800's, the 1900's had 297:with the majority of those in the 70's thru the 90's. Planted a lot of seeds around then and we continue to plant as fast as we can as a society. We are just unfortunately planting seeds that bear fruit we don't like the taste of, guns don't kill people , bad apples do.
