I agree. Anyone who doesn't is a fool. 

The thing about Trump's executive order is that it's done in the name of national security - when there is little evidence that it will do anything to prevent terrorism. There is a lot of evidence that putting a "muslim ban" (his words) in place plays into the narrative terrorist groups use to recruit. Bush and Obama were very careful to not say that we're at conflict with a religion - but that we're at conflict with terrorist groups who happen to be religious. When people on the fringe see the U.S. banning people based on being muslim - especially if that ban causes harm to them or people they love then you're helping the terrorist recruit. 

Western policies directly impact terrorism. From sanctions, to wars, to meddling with elections, to the way refugees are handled. It's very healthy to scrutinize the effectiveness of any policy. "Banning muslims" is a very big symbolic statement but I feel it's counterproductive.
