This has always bugged me about the census; the fact we count all individuals without verification of their legal right to be here. I believe there is an implied general understanding that the Constitution requires we count legal residents in the US by the very fact all other laws in the country are upheld and enforced.
The very fact that anyone in this country could defend the lawlessness exhibited by so many merely proves the insane are in charge. I have never been so livid in my life!
