I think it has to so with the mind’s ‘survival mechanism’. Basically the actual problem/issue/fear is so overwhelming that most people simply refuse to address it. The brain just shuts the scope of it out. They take a bit sized issue and deal with that.
The problem with that, natural as it may be to do, is that you can’t cut a head off a hydra and kill it.
Gun Control=Civil War.
There, that explains it.
