I don’t know this guy but I am willing to bet he is a decent person. Nothing about that comment is particularly bigoted or racist. And this is something that I hear all the time. People have no problem with the immigrants among them. It is their actions they have a problem with and the fact that they broke a law. They feel justifiable moral outrage that someone chose to do something illegally that they could have done legally and because of all that they get to mete out punishment. It makes sense and it is a pretty simple moral calculation.
Except that commenter is wrong.
