It isn't that they don't understand, because that would require them to think, it is that they are gullible and spoonfed what they should believe from the media headlines. Half the articles they link don't actually match what is said in the headline of the article, I guess reading the article is something they don't have time for when trying to get something posted here.
I have been watching the ICE website, and I cannot believe the horrible crimes some of these illegal aliens have committed in their own countries and then fled here! These are not people who could have came in through proper channels, EVER! I suspect most of the illegal aliens coming in have a list of crimes attached to them and/or their family in their native countries.
