''Why canít we just share the perfection of the Quran and the beauty of our beloved Prophet Muhammad (SWS)?''
The Coran is far from perfect and what beauty there is in the prophet? And is ti not idolatry to worship human for muslims?
Maybe they wouldn't be the villains if Islam hasn't tried to conquer the world since in its inception. The world don't need their Dawa even if it's better than liberalism. We already have paganism, christianism, indouhism, boudhism where we can take traditional elements to improve our society so we don't need any newcomers especially when they try to convert us.
it may have worked in middle east, but it's not for the rest of the world especially in the west. Even there, arabia, Iran, Lebanon , etc had already a flourishing culture before islam thanks in part to Egypt, India and Grece so I don't think Islam has done anything good for that part. What islam has brought mainly was the unification of warlike tribes so they could conquer neighbouring countries instead of fighting each other. It's the same principle has the mongols, expect of having an Genghis khan, they have their Mahomet.
And for leftist muslims, it's no wonder that they come to Usa or Canada, they are not welcome in their own countries so they go to places where they will not be percecuted and where they can share some values.
