If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one. (Immediately before; refresh the list-of-threads page before posting.)
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
I suspect people feel he gives a negative impression of lesswrong. And he will not go away with downvotes. Trouble is that it's not just that we disagree with him; often he is behaving in ways that are, not even wrong. If he were doing something wrong, it would be simple to say, "that is something wrong; instead of doing wrong you should do right like X". By being uncannily off, we can't even help.
