Stop whitewashing 4chan's history.
And the Zizian murder cult sprang out of the bay area rationalist community and trans rights advocacy, what's your point?
You say this like the rationalist community and 4chan edgelords aren't two circles with an incredible amount of overlap.

They are not.
Rationalists are the crowd that would attract typical Bay Area tech yuppies. Which is something that 4chan seems to despise with passion and makes merciless fun on.
Just go on /g/ (the technology board) and see any mentions of bay area, rationalists, or tech companies/startups. If you believe there is a significant overlap, then they surely are hiding it really well there by mercilessly mocking everything related to any of those topics.
