The Muslim ban didn't make me feel any safer. What it did do was produce a chill upon those looking to immigrate and come through legal means to this country to study or to work. I would know having been in contact with and befriending those who came here to do just that... they felt that it was punitive, and given Trump's past history of comments about Muslims, hard to disagree with them.
I'd just add that in terms of threats, the threat of domestic terror, particularly from right wing groups, seems higher right now.
