Sid, for someone who usually presents a solid argument, all you've done here is engage in ad hominem, false equivalence and obfuscation. You haven't addressed any of the issues. The notion that objective reality can be over-ridden by strongly held beliefs is just not one I can subscribe to.
That said, I think Linehan has lost the run of himself and become totally consumed by this. Unfollowed him a while back as it was both boring and depressing to read.
