The first amendment does much more harm. Lies become the truth if told loud enough and long enough. Teaching is as bad because the young minds don't have a basis in truth to be able to ferret out the lies until it's too late. If there had been a dozen journalists at the Sandy Hook school, none would have been able to stop the killing. Rant off.
Our government teaches the whole people by its example. If the government becomes the lawbreaker, it breeds contempt for law; it invites every man to become a law unto himself; it invites anarchy.
I no longer have any weapons. ;(
