I agree. I downvoted some of his posts, not because he might not have a point, but because he was using a style that I do not appreciate on lesswrong: unneeded profanity, half-formed thoughts, aggressive tone, and (I'll admit) bad spelling.
However, I would not (and did not) down vote this original post, which seems like a reasonable argument (from the POV of someone who has not watched whatever video they are discussing)
Iksorod and I made a Google doc of intro-level training materials for rationality / critical thinking. We'll keep adding to it as we find more stuff. Please comment with your own additions.
