Unsure where the author of this meme has heard either Lenin or Stalin call for left unity? Both were pretty clearly and consistently hostile towards Anarchism/Libertarian Socialism as well as what we'd call modern Social Democratic tendencies.
Only not including Mao because I havent read enough Mao and Khruschev because I honestly don't expect him to have written or spoken in particular about left tendency conflicts.
Really funny to just put "intellectuals" under Mao though.
If they wanted a remotely accurate meme they should have put "no unity with counter-revolutionaries" as the dialogue, since that at least gets at the core divide and argument of the conflict, both then and now.
Edit: Actually the more I look at it the funnier it gets, like theres no Kronstadt? You put "factory councils" over like the one specific thing everyone gets to hear about and have to have an opinion on? What is this, a crypto-Trotskyist meme?
