If you did start to voice that maybe the CCP did unnecessarily massacre some people at Tienanmen Square, or that maybe Lenin and Trotsky really didn’t need to slaughter all the Kronstadt sailors, or that maybe Lenin did betray Makhno just to consolidate power, or that the Stalinists who killed the Anarchists in the Spanish Civil War might have been making up reasons to again take power…

Then you’ll be assured by any ML friends you have, that all those things are either CIA propaganda or justified, and if you don’t follow that line, and if you bring it up regularly to others as a reason to suggest maybe this stuff isn’t so scientific despite the name, instead of keeping that to yourself, you will eventually be regarded as a ‘shitlib’.
