On Sjö's talk page (last edit)  he says he has been deeply emotionally affected by the edit conflict about Jewish and Muslim slaughtering (banned in Sweden in the 1930s because of influence from Hitler Germany) and he would feel better if I kept away and did not ever contact him. He is responsible for requesting a block for me on Swedish Wikipedia. His psychological wellbeing is affected by me having any contact whatsoever with him. My block on Swedish WP seems to be motivated by emotional considerations.
