Concerning: "'Unity'. This is What it Looks Like from My Side":The Vietnam War coincided with the Hippie Era. It really helped bring it in. Peace and Love were a big deal. There were plenty of other problems too. However, we didn't have a Great Depression or Great Recession. More people are more radicalized by bad economic times ushered in by stupid capitalists than by anything else that's happened so far in the history of the US.
The timing of Barack Obama was very unfortunate. Had the election been about two or three years later and had a real democratic-socialist thrown his or her hat into the ring then after building an organization ahead of time, everything might have been radically different and for the better.
As for Obama, he is not clean. He lied to all of us about spying on us. When his man, James Clapper, admitted that James lied, Obama did not fire him. Obama has gone after more whistleblowers than all the Presidents before him combined, and that was after he promised to protect whistleblowers (promised during his campaign). Just because the Republicans haven't gone after him doesn't mean he's clean. It means they agree with him on spying and on whistleblowers, etc. Obama also aided and abetted Hillary Clinton illegally destroying evidence. I could go on, but I'm tired of citing the obvious.
