It was very much of the tone "I am now going to explain to you why you are wrong", but it was still civil. Rough outline:

1) Quantum mechanics does not say that.

2) Strong anthropic principle is a bold claim you've failed to substantiate.

3) Saying "our current theories of the physical world don't work" is outrageous coming from a man who attracts other objects towards him with a force proportional to the product of their mass and inversely proportional to the square of the distance between them.

4) The physical processes underlying organic life are perfectly compatible with a lawful physical universe, and fairly well understood by the standards of many academic disciplines (and you should know that, because you're actually an expert on the subject). To date, no mental phenomena have demonstrated properties that violate the laws of physics.

5) "Tree in the forest" is an artefact of the semantic history of our language, and nothing to do with physics.

6) Remaining few paragraphs are presented in a needlessly confusing way to obfuscate some fairly straightforward ideas. Obviously things we label "optical effects" require optical devices in order to manifest in the way we perceive them. The mapping in the analogies is sunlit_droplet -> skyscraper / rainbow -> sight_of_skyscraper, but the phrasing implies it's rainbow -> skyscraper.

7) It's one thing to point to poorly-understood phenomena and go "woooo...isn't it weird and spooky and strange?" but it's another entirely to deliberately and erroneously subvert pretty well-understood phenomena to try and achieve the same effect. Please stop it.
