Europe bans ideologies all the time (e.g. Nazism). They're just as hypocritical in their refusal to ban Islam as Trump is in trying to ban a religion despite the first amendment (which only applies to US citizens, anyway).
Bullshit! Apart from Nazism little else is prohibited, the wearing of religious symbols in some workplaces, what else?
And if you ban a religion you target millions of people who have no truck with the kind of thing these morons believe (

Should we have banned Catholicism when the IRA were bombing London, Manchester and other cities and assassinating public figures? Or do you look at the reasons people do this kind of thing, isolate and marginalise.
Knee jerk over reaction, especially the American way (9/11 invasions!), bombing countries
(who had fuck all to do with it) back to the stone age and stealing their oil, if our idiot leaders at the time hadn't followed the “War on terror” we probably wouldn't have this shit going on.
We can't stop all of these people getting through, but hopefully we will respond calmly and with reason and leave the likes of Trump to shout in the wilderness with all the other wankers. Take a look at the “one love Manchester” concert going on at the moment, that is how it should be countered, not with more bloodshed.
edit; The concert line up is pretty shocking actually, Coldplay & Justin bieber for christsake! But the sentiments are good.
