What's also ironic is that luke, who wrote the post you're responding to, has recently argued at some length that it's important to acknowledge the relationships between LW and mainstream philosophy and in particular the places where LW/EY owe debts to mainstream philosophy.

A reasonable man might infer from this that he's not entirely blinded by groupthink on this particular subject.

Of course, that doesn't mean all the rest of us aren't... though we sure do seem to have a lot of internal disagreement for a bona fide cult.
