@Marxist > What does quoting Marx have to do with being knowledgeable about Torah?
Sorry, did not mean you personally. I meant to say that some old-time anti-Torah Jews had an ideology, such as Marxism, current ones usually do not and not oppose anything. You are right, even someone who knows Das Kapital b’alpe can still be an ignoramus, but at least, he was a dangerous ignoramus.
This “yeridas ha doros” is one of the interpretations of arba banim in Hagada: first generation – chacham, second – rebels, third – not sure why his father rebeled, fourth – has nothing to talk about, fifth – disappears unless we put him back into first. Note that this 4th+ generations are far removed from the original rebels.
