“Hard Line” or “Common Sense”?

In my opinion, it is not a “hard line” to say "If you follow a philosophy that preaches violence against non-believers, you are not welcome in the United States."  An immigration policy of “You must promise not to kill Americans whom you disagree with philosophically” is common sensical and reasonable.

The U.S. is by far the most welcoming country in the history of civilization.  America has welcomed immigrants from all corners of the Earth.  We have welcomed people of all faiths 

and no faith.  We have welcomed all races and ethnicities.  We are the most caring, compassionate, and inclusive people in the history of the world - bar none.

From a personal perspective, I enthusiastically welcome legal immigrants of EVERY race, sex, ethnicity, and religion who support western ideals.  We should NOT welcome people who follow a philosophy (metaphysical, epistemological, axiological, etc.) whose fundamental tenants include killing, oppressing, or subjugating nonbelievers.

The U.S. should follow a rational and thorough vetting process prior to allowing any and all persons to immigrate to our country.

Regarding Western ideals: immigrants must support the separation of church and state, they must respect human rights, such as freedom of worship, freedom of expression, and the rule of law.  They must support political rights, such as the right of representative government, freedom of assembly, equality before the law, and the right to vote.

If an immigrant (at any time) was a member of an organization or social institution antithetical to western values - that disqualifies them from becoming an American.  Is this overly cautious?  Maybe, but with imperfect information, we must err on the side of caution.

Let me explain.  An actuarial is a person who compiles and analyzes statistics and uses them to calculate insurance risks and premiums.  Teenage male drivers pay higher insurance premiums than other drivers.  Does this mean ALL teenage boys are more dangerous than all other drivers?  Of course not.  However, probability, based on actual experiences, shows they are more likely to be.

In the same way, Immigration policy must be based on probability.  

• Do all members of the Nazi Party pose a danger to Americans?  Probably not.
• Do all members of the KKK pose a danger to Americans?  Probably not.
• Do all members of religious groups that promote “death to infidels” and subjugation of non-believers” pose a danger to Americans?  Unlikely.
• Do all members of ISIS pose a danger to Americans?  Actually, the answer to this hypothetical is almost certainly an emphatic YES!

Bottom line is, to paraphrase Proverbs 13:20, “He that walketh with wise men shall be considered wise: but he that walketh with evil shall be consider evil.”  If you walketh with evil - you should NOT be allowed to immigrate to America.

Now, let me address your question, “How does Jesus feel about this type of discrimination?”  

First, let me point out the definition of the verb discriminate.  It means to recognize a distinction; differentiate.  Discrimination is the way we make decisions - it is not immoral per se.

It is clear how Jesus would respond.  Jesus stood up against those filled with hate in their heart, including oppressive religious leaders who perverted the will and word of God.  He preached God's love.  He would do the same to these misguided people.  Also, if they asked for forgiveness, he would forgive them and say "Go, and sin no more."
