I'm not against the hostility being shown towards tankies here... but it should be remembered that there are a lot of well-meaning and well-intentioned people who get caught up in the technocratic ideology tankies buy into. Let's face it... if you google anything about leftism you are more likely to end up reading about Marx and Engels than Bakunin or Goldman - and right-wing propaganda is as perfectly fine with conflating everything "leftist" with the technocratic (ie authoritarian) left as tankies themselves are.
If we are leaving some doors open for fascists and capitalists who turn against their programming, we should remember to do the same for tankies.
