I think it's an educational issue personally those against it don't truly understand the situation. The Muslim population of America is very moderate and modernized and they assume all are, but theyre not so much in that area of the world. For example something like 91% of Iraqi Muslims support Sharia law and the numbers are roughly the same for the same reason. ISIS has said they will infiltrate refugee programs and they have. Those who have immigrated to western counties in Europe are generally not assimilating into the society but living in their own micro-societies of only Muslims. I personally think we should stop ALL immigration from that area until ISIS is contained. It's not anything against Muslims in general, it's a legitimate security concern that has historical precedence, we have banned travel from counties due to terrorism threats in the past. People are being incredibly dishonest about the internet. He's referencing ISIS online propoganda brainwashing ever increasing numbers of Jihadis and suggesting we shut down terrorist websites.

The government already has a database of everybody in the country, it's been known for several years. Just because they have the information stored doesn't mean they know everything proactively though. With that said, even if it wasn't true of course we will have records of EVERYONE who comes here no matter what religion they are. Trump was talking about immigrating Muslims with that comment. Would you suggest not keeping track of people coming into our country from an area of the world that is at war, one of the groups saying they're going to send people to kill civilians?

As for the deportations while I personally disagree people seem to misunderstand his plan. He isn't sending police to deport 11 million people. He's planning to make it impossible to employ an illegal immigrant and remove all their welfare so they leave on their own. Then use agencies to deport the remaining and deal with the illegal immigrants gangs.
