Wow, a YouTube video, because there is no propaganda or falsehoods on YouTube. I could post a YouTube video saying that a space alien gave birth to Elvis's love child. Would you take that to the bank? But that is neither here nor there, bottom line here is you are praising murderous regimes and making generalizations and assumptions about things that you are unfamiliar with. Vladimir Lenin referred to your kind as "useful idiot".
