Why is restricting Muslim immigration bad?

I know that this sort of thread ends up with insult from the op towards those who answer so please understand that I acknowledge that most philosophers think such a restriction would be wrong and I am here to learn.

I understand that many people associate the physical look of people from the middle east to being Muslim and being Muslim to being a terrorist or someone who beats women and this is very prejudiced  since many middle-easterners are not Muslim and the majority of Muslims do not do those stuff. This is bad, I agree.

However it is true that the average Muslim has a very conservative outlook on the world. And since at least in regards to Europe we are talking about big numbers this I think matters  and  given that I (and most of us here on Reddit) live in a democracy, this could mean losing various important rights.

Moreover the cultural injection of this outlook could either cause a growth of Islamic extremism in case of sudden crisis (i.e. economic crisis) or if immigration is not well handled and in general it would put in the social system unpleasant values for those who disagree with them.

This seems to me good reasons however I take that most of you disagree, so here I am. I do not think I offended someone but maybe that's part of (my?) the  problem so I apologize.

If banning people with conservative outlooks on the world is what you want to do, then that is the policy that should be defended. Banning Muslims as a proxy for banning conservative people is unjust in two ways. First, many Muslims are not conservatives, so they will be unjustly banned. Second, banning an entire group of people because of their religion stigmatizes that group, and stigmatizing people because of their religion is unjust.

Moreover, if it's okay to ban conservatives from entering, it's not clear why it would be wrong to exclude conservatives who are already in the country. But it seems like it would be pretty sketchy to just round up all the conservatives in a country and send them packing. So it's not clear why it's any better to draw a line around the country and say "no more conservatives."

Finally, it's unclear that you're right about whether Muslims are in general "conservative" compared to others. Certainly the sort of person who wants to ban an entire religion because its culture isn't the desire culture is acting in a much more "conservative" fashion than someone who is uprooting their entire life and migrating to a new area with a new culture.
