"mostly all if not all Islamic nations do not allow other cultures to express themselves without facing the brunt of the ruling government there." Absolutely not true. I live in Malaysia and anyone who has been to this country knows that besides Islam, Bhuddism, Hinduism and Christianity is practiced freely. Indonesia the same. It also goes for North African Muslim countries etc. So, just as you claim that Muslims must follow the rules of the countries they migrate to, so must the non-Muslims follow the rules of the Muslim countries they visit or work in. I work with many non-Muslim colleagues and all they can do in the host country where they work is complain about Muslims and Islam. So, why did they go to that country if they knew that their rules and culture are different? Thus, if they want to practice their religion, they should remain in their countries, as you have stated.
You also stated, "There are cases of Islamic bodies asking for Sharia law in some states in the US..." Is this not part of their right, given by the mighty American constitution, to freely express their opinion? What happened to the freedom of expression, association etc? When it comes to Islam, suddenly ALL kinds of freedom is suddenly forgotten! Being half naked is fine, FREEDOM of wearing personally preferred clothes. However, covering your body when swimming, is banned. What a laugh! They are BREAKING their own rules! No wonder the high court in France over-ruled the judgement. It even stated that the mayor overstepped his powers! The mayors of ALL those municipalities where the burkini is banned, are ALL intolerant! Judging an entire community for the crimes of a few is INTOLERANT and UNJUST. Now, if a Muslim country would ban binis and half naked swimmers, then there WILL be an outcry of injustice, intolerance, backwardness etc. I think you have to re-think your ideas on intolerance. Simple rule, practice what you preach. "Freedom", if it really exists, cannot applied to one group and not another. A Catholic nun can cover her WHOLE body, even when going to the beach, but not a Muslim woman cannot! Wonderful selective FREEDOM. Nevertheless, I respect your view, but I certainly do not accept it. Ciao!
