....Then along came the progressive attitude that some ethnic groups are superior to others. This is a damnable and racist view that was foist upon the federal government by Theodore Roosevelt and Woodrow Wilson, in direct response to the influx of southern European immigrants at the beginning of the last century, most of whom were Catholic. Roosevelt and Wilson and their progressive followers thought these immigrants had too many children, children who would grow up to be voters and vote out their Nanny State central-planning values. So they began to encourage birth control and sterilizations and even abortions.
