Liberals make rules for the rest of us. They don't live by their own rules. What the ACLU is doing is completely in character with the conduct of the modern Left.
Pretty amusing to see the degree to which the ACLU is tearing itself to shreds about this issue. Though I will say this - at least they do this research on their own donors. If you have not given money to them, you are left alone.
Regardless, this is small change, compared to what credit rating agencies have on us. Not to mention the banks, who finance our mortgages. When you purchase a home via a mortgage, the mortgage is sold (along with all your vital stats - SS#, monthly income, etc.) in a secondary market. Who knows where this information is going - but it sure is unnerving, the degree to which we sacrifice our right to privacy when we sign a home mortgage.
