The moral values of an individual are as unique to him as his fingerprint. It is important to our survival that we all think differently lest we follow the example of the lemming. What we are seeing today, not just in the USA, but all over the world is an unhealthy level of intolerance for independent thought. Reminds me of Germany in the 1930's.
You paint a grim picture there, but I think you make a strong point. The challenge becomes, how can we teach perspective to the younger minds?
The government and news media focus on diversity that is truly only skin deep. Opinion diversity is so much more important yet as you well know is not tolerated. So if we are all supposed to think alike who gets the honor of having the collective mindset? You, me, Hillary Clinton, Donald Trump, or how about Charles Manson. Who should we all think like? Opinion diversity is the upside of free-will in my opinion. To the intolerant it is the downside.
