It seems that the NRA folks, et al. won't be happy until everyone, in bars, churches, classrooms, sunday school, beaches, parades, halls of congress, parks, restaurants, bingo games and PTA meets adorn their bodies with AR-15s with two 200 round affixed to their mid regions. Now, some will see that as an exaggeration, but it's the gist of it that's my message i.e, the direction that the gun guys and gals seem to be heading.
As long as Republicans can filibuster in the Senate, and they control the house, no, nothing can be done. That might change in 2024, we shall see. No, it's not 'culture' it's public safety.
