The 1960s were some of the best yrs. of my life. I remember them clearly. I was blessed to be born when I was.
All decades are relative to what one looks at. The optimist thinks it's the best of all worlds, the pessimist fears this is true. The optimist will see/appreciate the work of art, the pessimist will see/complain about the shabby frame around it.
It has been my observation politics is like the 2 anodes on the battery. One is negative, one positive. Both are needed to complete the circuit. It's obvious which anode you are.
Both Kennedy and LBJ were libs against the spread of communism. As our youths began coming home in body bags and awareness about what was going on in Vietnam increased, public sentiment significantly increased opposition to the war. Eventually, even the draft dodgers were granted amnesty. That speaks volumes.
Those left wing hippies formed a sizable city of 400,000 people for 3 days at Woodstock (1969) w/ virtually no crime or violence despite the absence of law enforcement. You don't want to see that any more than how Nixon surreptitiously interfered w/ the Vietnam peace talks in 1968 to get an edge in the election. There's no way to know how many lives that cost.
