Plenty of people I know believe illegal immigrants should be deported. The difference between them and people accused of being a Nazi is they don't go around calling them all rapists and murderers.

The problem isn't the claimed actions they want to take, its the dehumanization being resorted to.

You’re exaggerating greatly, of course. Among those deported are rapists and murderers, naturally, and no one has stated that everyone being deported or even targeted is one (the recent Hyundai bust comes to mind). I challenge you to find that quote.
