Not only can the left not meme, they also can't even identify common, widespread memes.
Okay, hear me out.
Starship Troopers.
The 1990's Starship Troopers was Paul Verhooven literally shitting on Heinlein's work and raping the source material with his anti-militaristic worldview, but it was still an enjoyable film. It was still humorous and action packed and silly.
It was still a quotable film. Almost thirty years later its still a meme-able film.
Now this might be the exception to the rule, but you can inject lefty garbage into a film and still have it be a good film.
(The twisted irony is how much aspects of the 'fascist' Terran Federation in that film could be applied to today's left, including the constant media indoctrination, the idea that the Federation can never be wrong, only individuals in charge, the whole "Im doing my part!")
