There should absolutely be a temporary ban. And the reason is very simple. Would there be such a ban in effect 2 years ago then there would be 14 happy families instead of 14 heart broken families who lost the lives of their parent / brother / sister by some ugly Muslims in San Bernardino. The above is a fact. Whoever is against this idea is effectively responsible for the San Bernardino shooting. So think if you wanna be politically correct or logically correct.
I know that there are a lot of nice Muslims out there and it IS very sad to put such a ban in place and I do feel bad for the normal Muslims but I am sorry, the United States is not a garbage pail. I know it sound bad and rude but the safety of the US citizens is before accepting refugees.
And we all know that it is impossible to use a filter here.
