"Roses are red,
Violets are blue,
There is the State,
And then there is YOU"

Professor Rummel's "Death By Government" is about the 20 most democidal governments of the 20th Century.

Only six of those were self-declared Leftists, plus one "maybe". 

Can we stop trying to make everything about the Left/Right seating plan of Parliamentarians in 1700s France?

It's pointless, divisive and cringe. Sheds heat but not light.
