Wrong sir, the ottoman empire initiated that before Europe, the Muslims have separated the Mosques and the politics. The government ruled by Qanoun or what we call today law.
In others of your remarks you seem to think that a Muslim states Union will be based on religion, which is not correct, only its underlying will be Islam, the rest will be Law, Economics, Education, R&D, Defense and the betterment of its peoples conditions, all legitimate aims with no malice against anyone.
Um, no. This is "Muslim tolerance" in which you can do (religiously) what the Muslim rulers tell you to do,
at best. The millet system in the Ottoman empire assigned you a religion based on the community you were from, and you had no personal say in the matter. That is not freedom of religion or conscious by any stretch. Taking 20% of the male children and forcing them to convert is not freedom of anything. Don't brag about that, be ashamed.
Religious liberty means the right to decide for yourself what you believe, not have it told to you by the state, in any form. It is between you and God. This is not the case in any Muslim country, including modern Turkey. Modern Turkey gives lesser rights to even minority Muslim sects. Non-Muslims will have their parentage checked before being allowed to enroll in non-Muslim schools. Etc, etc, etc.
Muslims apparently just have a different definition of "tolerance" than the rest of the world. Call me when you find a predominantly Muslim nation that believes and practices equality between persons, irrespective of religion. That doesn't mean you
allow them to do xyz, it means they can pick their religion, change religions at will, and there are no legal consequences for it. Further, the law does not ignore offenses against them because of their religious beliefs. The state doesn't take their property, or tax them differently. Their houses of worship aren't turned into mosques. They aren't killed as devil worshipers, and so on and so forth.
And, importantly, Muslims can decide to not be Muslim.
