There's a big difference between sending missionaries to hostile places, and letting hostile people come here.

Yes, Islam, Hindu, budhist, Judaism, Novus Ordo,  atheism, wicca, satanism and other false religions are dangerous spirituality and physically to Christians.   Most Christians don’t know the faith because they are involved with false religion and gods.  Everyday the first Commandment is broken.  We have Catholics including traditional Catholics who are friends with these people or even married them without converting them.   These people seem friendly but are really not.  Catholics are losing their souls.  And yes, this is an invasion without weapons they come to USA and get free housing, food stamps , free medical and hospitalization, free education while driving around with fake tags and insurance.  Then they are running for public office to establish sharia law.  90 of them are running for US Congress  American children are being brainwashed to accept these false religions in the Catholic and public schools.  Catholic parishes are just as bad. They encourage Catholics to read about Islam, Buddhism, and other false religions.  Moslems attacked USA on September 11,2001.  They have slaughtered Christians for thousands of years and they continue to do so today.
Buddhists and Hindus aren’t that peaceful either because they are attacking Christians.  

Pope Francis needs prayers because he is a poorly formed Catholic who was raised with liberal liberation theology which is big time in South America.  Pope Francis is scary.
