I'm not sure I'd say I'm being "charitable" when I guess that the vast majority of left-wing activists are not in fact cannibals.
It's a quote that justifies homicide of the wealthy class, popularised during the French revolution: "When the people shall have nothing more to eat, they will eat the rich"
The rich don't make good eating in any case, too greasy, too much cocaine, if you must then you'd really want to slow roast ...
