This still doesn't explain why Yarvin being present at a conference, giving a non-political talk on technology (presumably with no so-called "hate speech" content), represents a threat to anything or anyone at said conference. The answer is: it doesn't. He was removed because some politically influential leftists wanted him declared a non-person.
