It's also kind of stupid. As in, very tiny amounts the things that the "joke" tries to attack are based in reality. Its as if they cannot accept that large numbers of progressive or liberal minded people exist.
I think it's actually the reverse. Your critique is that the NPC meme ignores that lots of liberals/progressives exist.
The rightist promoters of the NPC meme would agree with that statement -- but they would say that it's because most are just acting as ideologically/memetically programmed automatons. Crucial to understanding this meme is that its promoters see "libs" not as literal bots, but as humans-with-bot-thinking, who have grown up on a diet of platitudes and mantras without deep analysis.
On the contrary, the left/libs/progressives (whatever you want to call them) on Twitter have had a habit of actually doing what you're saying, when they pull out the "oh look another Russian bot" troll. That meme actually asserts that the number of actual conservatives/right-wingers is literally small and being amplified by actual programmed chatbots.
It's a joke. The books are called The Berenstain Bears. Because surnames ending in -stain are extremely rare and surnames ending in -stein are fairly common, a lot of people misremember them as The Berenstein Bears.
This has spawned numerous conspiracy theories about the name changing. There is a group of people who seriously believe they've somehow travelled into a parallel universe where the only difference is that a children's book series is named differently. This theory is often referred to as "the Mandela Effect", which is named after how a lot of people mistakenly remember hearing about Nelson Mandela dying years before he actually did (and yes, these people claim that they've accidentally travelled to a parallel universe where the only difference is that Nelson Mandela lived another 15 years). The theory sounds like a joke, but its proponents take it dead seriously, and they've been known to start flamewars over it.
As such, a lot of people like to make fun of these conspiracy theories by concocting the most ludicrous theories we can think of.
Jeez. This is why I will never spend any real money on Amazon or Apple to purchase digital copies of movies. I want to be sure I'll still own those movies in 30 years.
I can't tell if this comment is in jest or not, but we actually are starting a bank in the UK to be a platform bank for fintechs across Europe and beyond. Happy to chat.
