This is a provocative question, Sven)))
So, what a terrible thing did you do, when you visited another city?
Well.... we want to say that we SHOULDN'T judge people. But we do. We decide every day whether we trust someone or not, we decide every day whether we fear someone or not, we decide everyday if we will help someone. Would you invite someone into the home of your parents? You must judge and decide.
So I think you cannot escape the question by saying "we shouldn't".
Nur Salaam- I like your thoughts in particular. thanks.
