no, of course not. however this person is not expressing empathy for homeless people, but disgust with them.

This post is less “It is so sad to see people living in squalor imposed by capitalism, I wish to lift them up out of this condition”

and more “eww icky homeless people leave behind poo poo needles, please sweep them out of my sight”

the USSR was an internationalist project, a group of several nations, and specifically Lenin carried out the October revolution on the (unfortunately mistaken) idea that the other European nations would soon fall to similar revolutions. Communism is an internationalist ideology, not a nationalist ideology. “Communism in one country” was a result of specific conditions imposed from the outside by capitalist imperialism, not the end goal.
