I agree with him to a large degree:
I personally see mostly problematic content from the left[0] but I guess that is partly my bias.
[0]: for example this comment earlier today that I thought[1] was absolutely crazy "I don't want to participate in spaces where religious white nationalists feel safe" - just try to turn that phrase around to "I don't want to participate in spaces where atheistic colored globalists feel safe" and see if it wouldn't be flagged to death immediately by everyone including me.)
[1]: someone had to tell me that this is basically an euphemism for nazi, to which I had to reply that I would prefer if we just said nazi then because then I could join in despising it.
