In regards to the second, communists and working class people are human, we are all over the place, there is no correct distinguished way to be a communist. So it can be both as others wrote. I remember having a Marx study circle with like 10 students, 2 PhDs and 1 - extremely funny and smart guy - who worked in a factory producing Trafos (very cliche I know) and whose parents were communists in South America and fled, and quite a few of us academics were pretty much shutting down the experience of him, cause it wasn't the German academic study circle style.

This site instead would've laughed with him and tried to incorporate the jokes and experiences into Marx exegesis.
