Are we required to admit anyone who wants to enter the U.S.?

Is Islam a peaceful religion?  Do they want to be good American citizens?  Consider this:

Omar Ahmad is co-founder the Council on American-Islamic Relations (CAIR).  In 1998 he stated that “Islam isn’t in America to be equal to any other faith, but to become dominant. The Qur’an should be the highest authority in America.”… (Article in San Ramon Valley Herald, July 4, 1998.)

In the wake of the murders of 14 defenseless citizens in San Bernardino by muzz killers, some Americans have called for a moratorium on Muslim immigration.  Democrats and media "elites" immediately reacted with horror:  You can't do that, they said.  "That isn't who we are."

Of course the Constitution doesn't say we must allow just anyone into our country.  Presumably the emperor and his lackeys and supporters in the media know this, so they try to shame you into committing suicide.

When people who have stated that their goal is to replace our law with their ghastly sharia, seems to me only a fool would support letting a bunch more into the country.

Of course if a political figure or media talking-head was bent on destroying the Constitution and our way of life, it makes perfect sense.
