It's understandable that some personal biases may creep in to the moderation processes, and I believe that this is a much preferable situation than allowing it to devolve into an unmoderated forum.
I assume that Elon the Nazi is too inflammatory for an HN discussion subject, where the emphasis should be on polite discussion of nerdy subjects, as per the guidelines.
As an aside: I posted a link about accelerationism (a worthy HN topic methinks) but it had the word 'capitalism' in the title and got flagged - it is a well produced and thought provoking video by the way [1], and not partisan-political at all.
