That being said, what I also dislike is someone who seems to have no core beliefs whatsoever and instantly runs to the "intellectual dark web" bashing "the left", without acknowledging that what he refers to is a rather vocal minority, nor acknowledging the authoritarian tendencies of "the intellectual dark web" and basically just going with whoever is willing to air his grievances in a completely sympathetic, uncritical manner. It smells of opportunism, rather than some sincerely held belief.
Then there's the question of whether it is wise to communicate such issues across your company in the manner that he did. I am not saying it's right, but the world is a certain way and if one wants to change it, he/she needs to also be prepared for the consequences.
