Your claim only stands if you believe that denying entry "on the basis of being 'islamic or non jewish'" is the right thing to do. If you do not think it is the right thing to do, surely you don't believe that expanding such criteria for denial is the right response. After all, doing the same wrong act, in response to a wrong act, doesn't make anything right. The right thing to do, in a democracy, is to act towards the right. Sounds like there were two lawyers, and a judge, who did this. Thankfully they thought otherwise than you.
