I really don't see how anything I wrote was that controversial; he's free to disagree and pursue his own beliefs, obviously. Everything someone says that's not wrapped up in formal logic or statistics is implicitly opinion; the fact that I find repeatedly saying so tedious and ridiculous doesn't mean I'm asserting I am somehow an arbiter of the One True Faith.

We all act as we think best. I can try to change how others think. That's about the start and end of it.
