I'll admit our immigration policy is messed up and yes, people should enter here legally.
They hypocrisy I see from Coulter is they will say they came here the "right" way. Well, most of their past relatives came from Europe where only means of getting here is crossing the ocean and pretty hard to get here illegally. Also since we needed a large work force, our immigration policy was much more open to accept large numbers of people.
I don't know if I can state that during that time they had a more open policy to European immigrants, which again they had a huge advantage over people from different regions.
