The fact is that this guy is harrassing me. He has continually deleted everything I have added to articles, he has thrown insults at me, he has refused to engage in any meaningful debate, he lies about his sources, he is highly disruptive. Administrators give him a free hand to do this, because they are too busy with petty and inane discussions on user boxes and such. There is a complete breakdown in procedure and no-one is doing anything about it.
