I notice the word "undocumented" has taken the place of "illegal". Does that make it more acceptable? As someone who has a green card, I split my time between the US and UK, I went through a lot to get a visa for the US even though I was married to a US citizen. What about all those people who right now are going through the process of legally entering this country, surely allowing people who just decided to skip this step is insulting to them.
Illegal means just that even if it's seen to be not PC to use that word now. You can't reward someone for doing something illegal it's that simple.
I was faced with being separated from my husband if my visa application had been turned down for whatever reason. The problem is that the immigrants I believe this thread is referring to are unable to be processed in the normal way, there is no way to investigate their backgrounds and as we've seen in Europe that is a dangerous, very dangerous situation.
I'm going to refer you again to WWII where the men of Britain went to fight the Nazis along with many brave men from this country who laid down their lives. Food was rationed, my grandmother and mother talked about how they would eek out food but their will to not give in was strong, they had no weapons if the Germans had decided to invade but countries like France, Belgium and others also fought quietly through the resistance and many, many of them were killed for doing so. If someone's country is being threatened then you stay and fight for it you don't run away.
Have you noticed that the majority of these immigrants are young men? As we've seen in Europe they've left the women of their families behind presumably to deal with the terrorists. The man who raped a 10 year old boy and explained to the judge it was a sexual emergency because he hadn't had sex in 3 months because he'd left his wife at home.
The official estimate is that one in five of these immigrants is an ISIS plant and this applies to the ones trickling across the border of Mexico, they've found that's an easy way in. It is in our nature to feel compassion for people who live in war torn countries but this is a different kind of situation than the world has seen before.
