OTL we can learn a lot by comparing music and the Spanish Civil War. Then compare labour movements in Canada with the USA.
During the Great Depression, American folk-singers like Woody Guthrie and U. Utah Phillips developed a whole genre of protest songs, mostly about poor working men riding the rails in search of work. Woody even wrote a song entitled "This guitar kills fascists."
OTOH when unemployed Canadian workers tried a march on Ottawa, they were stopped by a police riot in Winnipeg. It was much easier to stop the March on Ottawa because Canada only has one or two railroads that cross the entire country and they converge in Winnipeg. East of Winnipeg, the railroads have to crosses hundreds of miles of thinnly-populated forest with only the occasional mining or logging town in Noryhern Ontario.
Few of these unemployed men (Canadian or American) had Marxizt-Leninist leanings, because their interest were more towards organized labour unions to ease the plight of poor working men.
Another amusing comparison can be made between Americans and Canadians who volunteered to fight in the Spanish Civil War. American volunteers tended to be well-educated, middle-class communists. American volunteers were dedicated communists but had little experience living-rough.
OTOH Canadian volunteers included more recent immigrants from Finnland, Hungary, etc. who had ridden the rails in search of work in logging camps, farms, mines, etc. so knew most of the tricks to living-rough, which made them tough soldiers. However, when they got to Spain, political Commisars complained that Canadian volunteers "were not communist enough" questioning orders, deserting, etc. Canadian volunteers did not blindly follow authoritarian communist officers.
