Yes, it is regrettable that the Islamic political system is not fully implemented anywhere in the world today.

Ouch!! I am glad it is not. It is really barbaric in most cases. Imagine living in such a country as a non-muslim, as a second-class citizen. Imagine not being able to preach your religion openly. Or worse imagine leaving Islam. 💀

Or, even worse, living as a girl. Or even more worse, as a homosexual (astaghfirullah). Imagine going back to the political system of 14th-century Arabia.

Not even remotely close to being just, fair or equal. (Sit down once with an open mind and try to research every topic by yourself, without any biases and you will come to a similar conclusion).
