Possibly, but the situation is so hypothetical and far off that nobody can say what exactly will happen.
Bear in mind that people used to say the same thing about Catholics.
What do you mean? The situation happens in every country today where Muslims form a majority. It happened in the streets of Bangladesh, where an unarmed Christian missionary was outnumbered seven to one.
As for what people said about Catholics, maybe they were right. Maybe they still are right. There may be individual good Muslims and good Catholics (including in my family) but history tells us that Catholicism as a religious movement has been most mendacious.
Bringing up Catholics doesn't change the fact that everywhere Muslims have power, they use it to oppress others.
