The most tragic thing is that what knapp said is right, and it will be because of the ban.
This makes America much more dangerous, not safer. The best possible thing for our country is to welcome the Muslim, welcome the poor, welcome the refugee, welcome the downtrodden, then learn, interact, love and grow together. Want to guarantee terrorists keep trying to attack our country with unrelenting radicalism? Paint the United States as being anti-muslim. That makes their recruitment and their propaganda indoctrination that much easier. That makes our country that much more at risk. Fortunately for Trump, that also gives him the ammo he needs to justify trying to literally destroy world peace.
