Not all Muslims are terrorists but all terrorists are Muslim.
Trumps point is that we should not be bringing large numbers of these people into the country. Nobody really knows what it is about the religion that sets off violent crime. Our first concern is the safety of our citizens.
The religion seems to have a component that is incompatible with western civilization.
Not even close, while most current terrorists are Muslim, the Provisional IRA, Bader Meinhof Gang, the Italian Red Brigades, and FARC in Colombia are or were examples of non Muslim terrorist groups.
Historically the KKK, Viet Cong, and various anarchist groups would qualify.
Islamic terrorism is just the most prevalent current flavor of man’s inhumanity to man.
If there are moderate Muslims, they are heretics according to the Koran. Real Islam is incompatible with freedom and tolerance. It can’t coexist in peace.
