My point is that terrorists aren't only Muslims, and there are possibly more home-grown terrorists than incoming terrorists.
Even the local thug entering your home can cause terror. That is not how we use the word 'terrorism' nowadays!
Yes...there are many domestic problems in every country. Racism, police atrocities, mad cap killings and so on. Even possibly home grown religious fanatics. These obviously need to be tackled at their level.
But how do these problems justify allowing more and more ISIS fanatics into the country, knowing their agenda and ideology?
The issue is ...how do we identify such fanatics and isolate them from normal muslims?
Until we have some clear way of doing that....all muslims migrating into any country would have to be viewed with suspicion. Unfortunately, unlike earlier times...gender, age, education, race, nationality or any other category cannot be ruled out automatically as beyond suspicion! That is the problem.
