It's pretty striking just how many criticisms aimed at communists are probably more accurately analysed as problems flowing from whiteness, patriarchal and heterocisnormative social dynamics (particularly those influenced by "Western" philosophies and politics), ableism, or just plain old negligence and recklessnessโ
Which is to say that they all highlight the importance of developing and maintaining good political lines on issues that aren't of a "purely economic" nature. A lot of the most critical areas for organisations to actively improve their positions, and make those positions a wedge issue, are a lot of areas that just weren't written about by Marx, Engels, or the Old Bolsheviks.
If a given general theoretical approach has guided tens of (at least temporarily, and at least partly) successful revolutions, then it's clearly robust enough that we can actually learn from the mistakes and deliberate bad decisions of people who've applied it before, rather than trying to leave the source material "unaltered".
