There’s quite a few things that happen throughout the episode that make implications that Matt Stone and Trey Parker are pushing back against a large swath of reactionaries that claimed them last year. There’s also plenty of stuff that runs contrary to their supposedly libertarian leanings. The contextual implication that Hillary Clinton, although boring and not necessarily morally “what we need,” is probably who should win the election because the other guy has literally been making horrible promises and has no plans — but also that it would be really nice if we had a system that would allow third parties. They also, very subtly, implied Bernie Sanders would have been a better candidate — something that will likely go unnoticed, but it’s there.

There’s something specific I want to talk about, though: Memberberries. These little guys have cute little voices, cute little faces, and appear to be totally random. At first, I wasn’t sure why they looked like grapes, but I figured out they are are actual sour grapes. Using structure and context, the Memberberries link obsessive fans’ nostalgia with bigotry (which is actually a big problem) and pretty much repudiate the entire movement that attempted to take ownership of the idea of liking South Park itself last year.

They set up context that begins with the need to “reboot” the national anthem (because of Colin Kaepernick, of course). The country believes that J.J. Abrams is so good at rebooting things, so they need him to do it — keeping the best parts of of the anthem intact, though.

Then, at an assembly, Cartman (now a Woke White Male Feminist™ — side note: he functions as a pretty good criticism of that type of person) talks about internet harassment and that he overheard some other male students saying the new Ghostbusters “sucked balls.” This is important because it’s mentioned specifically to remind you that on the internet, there was a very male backlash over the new Ghostbusters — which was also a reboot.

Then the Memberberries make their first on-screen appearence. Their schtick is comprised essentially of remembering how wonderful Star Wars and other pop culture touchstones were. So J.J. Abrams has been established as “so good at encapsulating what makes things great,” Cartman has reminded us that there was a sexist backlash regarding the Ghostbusters reboot, and the Memberberries exist to talk about the good ol’ days.

The berries then ‘member Ghostbusters. In this context, because Ghostbusters has also been rebooted but was not received well when compared to Star Wars — the implication is that these grapes probably don’t like the new Ghostbusters — after all, what is the point of reminiscing about it if they are satisfied with version that came out a month ago?

They are both literally and figuratively sour grapes.

In the final Memberberries segment of the episode, the berries expose themselves to truly be nostalgic for the good ol’ days by exposing themselves as racist, homophobic, and xenophobic. The berries ‘member “being safe,” implying that liking the old Star Wars (without the black people), remembering the old Ghostbusters (without the ladies), disliking the fact there are so many people of color around these days, disliking gay people’s right to marry, and fear of ISIS and Islam all make a certain group of people feel “safe” — and that this group of people is pretty forward about their tastes in all of these categories of belief, most likely because it makes them feel (again) safe.
