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.
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.
