Have you by chance read his letters to Engles?

"Is it a misfortune that magnificent California was seized from the lazy Mexicans who did not know what to do with it?"

-Karl Marx

"Being in his quality as a hard R slur removed, a degree nearer to the rest of the animal kingdom than the rest of us, he is undoubtedly the most appropriate representative of that district."

-Engles, regarding Marx' son in law Paul LaFargue, who Engles said possessed "one eighth or one twelfth hard R slur removed blood."

Bonus points:

"The Negro is indolent and lazy and spends his money on frivolities, whereas the European is forward-looking, organized and intelligent."

-Che Guevara

Why idolize such virulent racists who say things that would make even Ted Cruz (Cruise? Kruz? Fuck it) blush? Seems like it may be a bad crowd to follow.
