No, before Totalism the left-most ideology was simply called Bolshevism or Leninism. I forget which.
It was "Bolshevik" (source: I remember when Totalism came out)
It's kind of weird to me seeing how people are defining "memey" things, since quite frankly I've viewed a lot of how HOI4 KR presents itself to be pretty memey. "Direct Rule From X", basically everything to do with Long, that sort of thing. In the game itself (now that I finally caved and bought HOI4 this month) it's less so, but it really looks to me like the current team loves to lean into memes. Stuff like La Plata, Fuhrer Wrangel, most of China, doesn't strike me as memey at all, more just legacy stuff from a way earlier internet that didn't have the research capacity we have today that people were unwilling to change because hey, it works and who wants to stomp all over someone's hard work. Hell, I did the same thing when I made Transcaucasia with all the espionage events. Looking back, all those events suck and should be axed in favor of actually fleshing out the socialist Caucasus, but I didn't want to feel like I was trampling all over the mod. Also it's a bit funny to mock La Plata when at the time of its conception it was one of the few exceptions to another AH trope of Nothing Ever Happens in South America. It wasn't super plausible or accurate but it was trying, which is more than you can say of some TLs on this site right up to this day!
So to be cutting Blair due to "plausibility" rings weird. Especially when KR devs have been totally fine with Totalism just being "what if Syndicalism but
eeeevil"* since its inception. The whole point is to be a historical in-joke where George Orwell helps create Airstrip One! If you constantly invoke plausibility over a)interesting gameplay, b)interesting setups/outcomes and c)the occasional "see what we did there" (although it'd have been nice if they were more subtle than "this time the CSA is leftist and in the north!!") then eventually you're going to wind up at a place of OTL being the only of all possible worlds and at that point just, I dunno, go read a book or something. I'm not saying plausibility is unimportant, but eventually you're more concerned with pleasing nit-pickers than making an engaging game. KR has been almost continuously blown off by this very website for being implausible, and all the changes to the mod over the years really don't seem to have done anything for that. At some point, you have to wonder why even bother.
*If I ever get back into DH modding then I'm starting the "make a Bad End for a leftist country that doesn't invoke Stalin/Mao or 1984" challenge for KR
