Founding father of liberalism?

You do realize that your statement only proves to us how little you know about Marx or liberalism - or history for that matter.

In case you are curious, liberalism originates in the Enlightenment period and is represented by late 17th century English Whigs, which is some 200 years before Karl Marx ever published a word.

There is nothing even remotely liberal about Karl Marx's work. And yes, I have read (and formally studied) most of his published academic work.
