Terrorist groups such as ISIS have been targeting any civilians who disagree with their vile ideology which is completely contradictory to Islam. This includes Muslims who are following the original Islam and not participating at all in any terrorist activities. Discriminating against Muslims just because of a possibility that they could be linked to Islamism is unethical and contrary to American values. America was not built on Christianity. The idea that America must uphold Judeo-Christian values is based upon a limited world view and is frankly wrong. The first amendment secures freedom of religion, and discrimination in our immigration system is just as bad as public discrimination. We should continue to accept as many refugees as possible as all of these people are fleeing violence and persecution. It is morally wrong to turn them away for any irrational reason, be they Muslim or Christian. Our current vetting process is very sufficient, and there have not been significant signs that jihadism had infiltrated our country.
