Gosh, farmer, which museum did you find this in? It honestly doesn't bear scrutiny in a debate held in 2017. I guess that's Bernie Sanders illustrated on that-there poster. Mighty odd -- doan look much like him ...
What FF has picked up on is that fascists use POPULARISM to get into power. Now it just so happens that leftist ideals are often, much as he might wish otherwise, more popular than right-wing ideals. Though the Tea Party is founded on similar ideals to the French Revolution and the Communist marches - overthrow the elites - except the Tea Party types are happy if their own types become the elite. Four legs good, two legs bad. And FF will gladly go to the glue factory if ordered, provided no filthy human (Democrat) ever gets near the White House again.
You are misusing words again. The X axis is left right and the Y axis is authoritarian to libertarian. One can be either left or right yet still be high on the Y axis making them either the authoritarian left (communist) or the authoritarian right (fascist). Being authoritarian left in no way makes one "fascistic", though they are both authoritarian ideologies. Words matter. Please try to learn their definitions before you throw them around incorrectly.
Shit, Mao used populism to gain power in China (demanding land reform and an end to rents) so it is hardly confined to the right.
