It should only make the community nervous if your eventual intention was to convert everybody to shop on sundays only Plus when the community discusses and debates with you, you would be giving logical reasons to support your argument and not stuff like "Stephen King's novel says that I must shop on sundays so I have to". I think you get my point

You are probably right about there already being seperate days for men and women. Could it be that the demand was for muslim seperate days? I don't know the details apart from the quote I posted.

Fair point but the flip side would be that if you are minority in a community then your opinion won't carry same weight as the majority community (irrespective of the merit of the actual argument).
