If Holden were a major contributor, your argument that the LW editors demonstrated their tolerance for dissent by encouraging the criticisms he made would be bogus. Suppressing the comments of a major donor would be suicidal, and claiming not doing so demonstrates any motive but avoiding suicide would be disingenuous at the least.

If he's not a donor, my apologies. In any event, you obviously don't know that he's a donor if he is, so my conclusion is wrong. I thought Yudkowsky said he was.
