@namark Agreed, though if we are to kick him out it is more likely to do with if he is disrespectful or not, and he has crossed that line a lot. So it is worth considering.
I'll talk about it with the other moderators.
It is very concerning how he talks like a flat earther, asserting things he thinks are true, but known to be false, then making up absurd things proven false many years ago to sell his snake oil.
It certainly isnt the type of people we want as a server of scientists, but I need to be careful how we handle it as moderators.
