I've seen my supposedly smart and well-read friends dismiss the lab-leak theory out of hand; rejecting all discussion and labelling me with the right-wing conspiracist label despite the fact I'm heartily left-leaning.
And, I have a lot of experience with political posts on Reddit being "ninja-banned"; appearing in New but not in the main feed; disappearing even from new for an hour and then re-appearing, comments ninja-removed without trace, even from their OP's direct comment feed.
Poor Aaron Swartz :/
