Banning Muslims from entering the US is probably better from the alienation perspective than letting large numbers of them in, and then having to police them heavily to prevent attacks like the above
I disagree; discrimination doesn't lead to greater mutual respect. And since the percentage of respective offenders between Muslims versus non-muslim is a rounding error, singling them out as a group is also highly inefficient, to say the least.
I said nothing about mutual respect: I was merely comparing the pro-ISIS propaganda effects of "they won't let Muslims into country X", and "the Muslims in country X are under continuous police surveillance".
