The left has a tendency to evaluate theories in terms of their thinkers in order to weigh their "legitimacy". This is a very unhelpful practice, it would be better to disregard the origins of ideas and pick and choose what is currently useful. I think the views of "no heroes" and "ideas, like a supermarket, are only fit for looting" are appropriate in this regard. The leftist theory-nerd tendency to bring "problematic" stuff up about past and current figures is only a symptom of their desire for heroes/villains (which they see as being subject to vetting to fit into their respective categories).
Here are some examples of what I mean:
When liberals, observing that Trump wants to pull-out the military from Syria, or get the U.S. out of NATO, uncritically react by siding with the American military's imperialist policy.
When some people consider Audre Lord "problematic" or "cancel" her because of her views of the BDSM community of her time (which frequently used raceplay) and use that as an excuse to ignore her feminist ideas.
You likely don't like Trump, but like Audre Lord, but the point is that IT DOESN'T MATTER.
