Oops, I haven't read the end part of your post. I hope you did't mention me, as I din't know anything of the Communist Manifesto. Just to know: I'm living (and was born) in Hungary and it was the part of the so called "Eastern Block". So it was mandatory to learn toroughfully about this work (I have a copy in Humgarian), and about Marx, Engels, Lenin. Even we had to learn to Russian. This whole era was terrible. The soviets was here 40 years, as they say "temporarily".
Sorry if you didn't mention me, in this case this reply is not for you.
