I don't understand why this is being fought so hard? Why not know exactly who is coming in? Why not try to understand the intentions of incoming immigrants?

I lock my house doors, even when I'm home. They are locked twice, once with the lock on the doorknob, and once with the deadbolt. This is on all three doors.

I don't lock my door because I hate my neighbor, or hate the family walking on the street, or hate the lady driving up my driveway, or even hate the guy knocking on my door. I don't hate the folks on the outside of my door.

I lock my door because I love the people on the inside. I'm trying to protect myself, my family, my possessions, and even my pets.

I will make sure I want to unlock my door, before I actually unlock my door. Would it make sense for me to ask a stranger who he is and what does he want... while he's already standing in my kitchen, with my butcher knife?

VET INCOMING IMMIGRANTS. I didn't say deny entry forever... just til we are sure we want them inside our kitchen. Cuz the butcher knife they can weild might be to cut up dinner... or it might be to murder us where we stand.

You seem to be quite confused. Refugees and immigrants from these countries already go through a long, rigorous vetting process, so you should already be happy.

In fact, it's so rigorous that more Sikhs mistaken for Muslims have been killed by right-wing American terrorists than people in the United States have have been killed by immigrants and refugees from the, now six, countries affected by the Muslim ban (that number is zero, for those keeping count).

Very curious that Muslim-majority countries where Trump owns property are not included in this ban. Also very curious that Christian-majority countries with known terrorist problems are not included (eg Venezuela, Colombia, Russia). I agree with the previous poster that if you want to exclude individuals with terrorist ties, then do it with the existing visa process. Blanket bans based on nationality or religion based on questionable stereotypes are clearly illegal.
