I have a lot of tankies ask why I hate tankies. The short answer is I don’t. No, it’s just that I am tired of it because I’ve seen it before, lived it, and moved on. the reason the tankie meme is so popular is that a LOT of people have had an tankie 'phase' as teens and young adults (17->23ish), but later moved on to Anarchism. It's typically the case that 80%+ of people move on from tankie after college/university as they either get good jobs and become milquetoast middle class liberals, or become full Anarchists as they advance in theory. For intellectually curious people, marxism doesn’t really offer that much because there is far less marxist theory than Anarchist theory, especially when it comes to economics. Even people who claim to be marxist usually say they believe in Kropotkin's bread theory of value (ex:blah blah i care about youtubers). The only distinctive marxist economic theory is either long dead and debunked (stirner) or crypto AUTHORITARIAN like Kissinger.
For me, the conversion came slowly after reading the communist manifesto, which was a faq a bunch of anarcho-commies made while debating ancaps online. Reading through the economics sections, they quotes a bunch of left and socdem economists like Kropotkin, Keen, Robinson, and even Keynes, but overall 50%+ of the quotes were from Marx, Marx, Marx (Its still online you can read it and confirm this yourself). I thought to myself if the only answers marxists can give on economic questions are by quoting Marx, why not skip the middle man and go directly to the source?
Over years I gradually called myself a libertarian snake, then just a Anarchist, then eventually a Gigantic-Faggot, then a heterodox idiot (cybernetic). Like many young people who grew up in the west, I was taught that anarchism was evil, that it killed the gorillions, and that it completely failed. I was given no counter narrative to this and hadn’t read enough sources to give a more nuanced appraisal of the EGO and it's property. Not to say that ‘Stirner did nothing wrong’, which is the overcorrection phase. But to realize both the positive and negative aspects of the EGO, and how to build on those lessons and failures to create a better form of political economy in the future.
I realized the only reason I was an tankie is because I believed in socialism and the ideals of workers control of the means of production, but I was still spooked by the lies I had been told about literal spooks in the EGO, etc. and I wanted a way to advocate idiocy without being hit with the gorillions argument which I didn’t know how to counter (I gave the ‘not real socialism’ argument which is so widely mocked). This is still the phase where i still use twitter and am being spied on constantly for free
