Bombing predominately Muslim countries, overthrowing governments and covert black sites where Muslims get tortured. These are things that are acceptable, but a 90-day ban on immigrants coming from war-torn countries, that's a step too far? Has everyone seriously lost their mind?
(The same applies to British politics: yes, the Labour party were wrong over the Iraq war, but does anyone think the Conservative party were in the right, or would have been less keen to support the US in that situation? Especially given the May-Trump summit.)
