Name a dozen influential 20th-century American:
-leftist labor organizers
-leftist political agitators
-grassroots (leftwing) political organizations/parties
-reforms resulting from leftwing agitation
-leftwing periodicals
-leftwing intellectuals
If you can't do this in fairly short order you're in no position to say fuck-all about "The Left," its legacy, or its "principles."
