# US Presidents assassinated: 4. http://en.wikipedia.org/wiki/List_of_United_States_presidential_assassination_attempts_and_plots
We had mass protests in the 60's and 70's. That's 40 years ago.
Kent State Massacres were in 1970.
Not saying 'above reproach' but theres a difference between these things. I'm unaware of anywhere in the US where there is a curfew with a death sentence attached.
We also haven't whisked away our senior military and other heads of state and 'vanished them'. The USSR, Cuba and other communist nations however...did.
Before the Revolution in Russia there were regular pogroms with thousands being killed, that was a capitalist society so the communists took over and killed people so what was new? People kill people, always have done always will, regardless of their political beliefs. communists are no worst or better than anyone else. I doubt being a slave in capitalist America was pleasant, they were hardly allowed to wander freely were they? Even released they still had a stinker of a life dodging capitalist lynch mobs.
The point is that it's not the systems it's the people, to be so afraid of communism and as Sukerkin says to froth at the mouth about it is not attractive in a country where the people pride themselves on free speech and being reasonable.
