What plantation?
If it is Democrat oppression, why are liberals and leftists trying to tear down Confederate monuments and the right is crying to keep them up, and defending people like Robert E Lee? (https://www.youtube.com/watch?v=N839Z38w_AU)
Antifa (the organizations) are primarily leftists comprised of socialists, communists and anarchists, not Democrats, though some liberals are involved.
Your criterium for something to be leftist is for it to be statist? What about the fascist right-wing governments of Mussolini, Francisco Franco and Augusto Pinochet, who all embraced strengthening corporate firms and privatization? Right-wingers adhere to hierarchy, because they believe it is natural and even desirable. Leftists believe in an equal, egalitarian society, where there is less hierarchy (especially pertaining to class) and some leftists, such as anarchists, do not believe in any hierarchy whatever.
