When are we going to face the fact that the United States is a sick society?
Before we can make America great, we must make America sane again.
If our society was sane, we wouldn't have these recurring mass shootings, thousands of other gun deaths, other types of murders and gangs roaming around our cities killing each other. We wouldn't have hundreds of thousands of homeless, nor millions slaving away at an inadequate minimum wage, and companies shipping our jobs overseas. We wouldn't have so much violence portrayed in movies, television, sports and video games. We wouldn't have our military stationed in hundreds of bases around the world to intimidate other countries to conform to our expectations; nor would we have a country saturated with handguns and assault rifles. The problem is not the rank and file of the membership of the NRA, but of the gun manufacturers and their toadies that run the NRA.
It's very disconcerting that the United States, one of the most religious of the Western nations, is the most violent with the highest proportion of its citizenry incarcerated. Also the more religious states dominated by fundamentalism have the most violence. Why? This may have something to say about fundamentalism in religion.
Also we have members of congress that are spineless (some say they are evil) and bought off by the gun interests. Shameful. These politicians have no honor and need to be defeated at the ballot box. Happily, more women are entering political life and being elected to public office. The human male has been the primary perpetrator of violence and war since time immemorial.
