This is a Nazi joke, the Nazi Party(while not actually being socialist in any way) was short for the National Socialist German Workers Party. And again as we all know the Nazis not only weren’t socialist but actually murdered people that were, they just co-opted the name, they were fascist authoritarians. Other countries that weren’t/arent actually socialist or communist but rather authoritarian state capitalist are the USSR and the PRC. Lemmygrad’s grade of “socialism” is from what I’ve seen, straight up authoritarian like those two “communist” countries, thus the OP is saying they are in support of the national socialism otherwise known as nazism
