Granted, some Muslims will convert away from jihad. But the problem is that some won't. There are even some who will convert while they are in prison after they kill a few infidels. Are you willing to expose your family to the increased likelihood of Muslim jihad shootings, knifing, rapes on juveniles (Muslims think kids are fair game as so did their big M) and attacks on our way of life as is seen in Detroit?
The people being brought into the US need to convert BEFORE they are admitted. There is no way possible to screen Muslims from: will they or won't they kill jihad?
