The problem is not Islam or Muslims. The US constitution protects the rights of US citizens and legal residents regardless of religion and specifically prohibits discriminating on the basis of religion. The problem is a small group of terrorists and Muslims who are training and converting Muslims to terrorists with the "converters" often from outside the country. Many countries are facing this problem-- which can come from action and teaching within the country or from outside the country using the internet plus travel. We need to find a way to do this in the US constitutionally and with the help of the Muslim community-- more active help is needed. We need to prevent those who are converting and radicalizing from entering the country (and do so in a way that is not violating the constitutional rights of US citizens who are muslims). Discriminating against Muslims or Islam will lead to more terrorists-- human nature.
