Eastern Marxist is a traditional catholic now? Come one dude, you must be kidding.
From what I am gathering, I guess my development was the most "healthy" one. Starting from the age of 15, I went from a patriotic SocDem to regular Marxism to Marxism-Leninism over the course of three years and have been a Marxist-Leninist for the last seven years. I don't think this is ever going to change considering I sort of organically developed this view by slowly reading stuff over the course of several years and figuring out what makes the most sense. The whole SJW craze started when I was already a Marxist, and I was genuinely confused by it. The whole thing about being "pro-IdPol" or "anti-IdPol" was something that was completely alien to me, as any dialectical materialist would recognize the superstructure being in a reciprocal relationship with the base and that an isolated focus on any of these things leads to either liberal idealism/reproduction of the capitalist system or a too mechanistic view of DiaMat. Well, things sort of overwhelmed me, suddenly I got attacked by comrades for not having a stance concerning this and that pronoun and as someone who's never been interested in gender theory I couldn't give an educated answer but I guess no matter what answer I'd have given I would have been smeared by either side.
Since 2011, when I started being politically active, I experienced a whole new wave of people coming into Marxism who came from a very different perspective than me or my comrades from that time. A lot of them came from the SJW train, and merely accepted Marxism as a holdover but clearly didn't really care too much about it because of all the problematic stuff (such as Marx viewing colonialism as a necessary step in the development of productive forces). You usually don't have the time explaining the difference between traditional colonialism and modern imperialism to these folks because they care more about an identitariann conception of who they consider oppressed.
Another wave arround 2015 consisted of people being very much concerned about immiseration of the working class and growing inequality. This was a good thing at first, because at least these guys came from an economic angle. However, most of them weren't interested in Marxism either, all they wanted to do is to "modernize" Marxism, make it more relatable to people, which basically comes down to an alternative version of social democracy. They'd go on about big business, CEOs, money in politics and all that, but weren't really interested in what Marxism or anti-capitalism in general was about.
The last influx of new folks into the radical left, as I experienced it, happened arround 2016 - the "anti"-people. They weren't concerned about capitalism at all, and while bearing similarities to the SJWs, they weren't as obnoxious but absolutely useless at the same time. They were anti-Trump, anti-UKIP, anti-AfD, etc., this was their main motivation to join a leftist movement, to "set an example".
Regarding the internet left, it didn't really kick off before Holla Forums was created. Before that, it existed in obscure forums, yes there was Jason making videos from his basement, but that was about it. I guess it cuts both ways, of course being an edgy Marxist seduces people in becoming one to get publicity. Muke is good example of that. On the other hand, internet culture can also revive the dusty parts of Marxism - Pierre Tru-Dank, who started as a shitposter, evolved into someone whose content I genuinely enjoy and managed to give such a dorky old thing like DeLeonism a fresh look.
The only thing that I can't stand are "leftist" Discord servers. I think everybody who engages in them should be shot.
