Does it make any difference who said it? It has a nice twist into it - just like the "Wenn Ich Kultur hoere, entsichere Ich meinen Browning" or "It's I who decides who's a Jew" - both attributed to Hermann Goering even though they were actually said by someone else.
Does the fact that that a saying was or was not uttered by a reprehensible monster make any difference? What does the Stalin's persona add to the realization that, after all, for some people four walls are indeed a waste of valuable real estate space. Or that what passes for "Kultur" is often a bunch of hogwash? Or that identity politics is but a shell game?
