He is really annoying. He is flooding python-ideas and python-dev lists with emails without trying to understand answers. He didn't understand that the Python community is not working for him.

IMO he has a negative effect on the Python community. When he asks a question, he doesn't try to understand how Python is designed and let people think that the Python design just sucks (which is wrong, Python design is great! Python is the best language!).

I'm skipping most Anatoly's messages for all these reasons.
