Again, semantics. It's being called a Muslim ban because it _only_ affects Muslims. Sure, it doesn't affect _all_ Muslims, but it still singles out one religious group.
It's being called a Muslim ban because Trump called for a Muslim ban, shifted the definition many times, and then issued this order with similar justification and overlapping provisions to many versions (though not identical to any version) of the Muslim ban.
It neither effects all Muslims nor (since it includes a temporary complete ban on all refugees) only Muslims, but it's still overtly targeted first and foremost at Muslims.
