Constitutional Originalism

I was persuing the postings over at the Huffington Post and came across this piece about the originalist interpretation of the constitution by some of our Supreme Court justices. Part of the article:

According to originalists, the Constitution severely limits Congress’ authority to prohibit pollution, hazardous working conditions and discrimination; permits state governments to discriminate against women, ban contraception and regulate private, noncommercial sex between consenting adults; outlaws independent enforcement agencies headed by officials who can’t be removed by the president, like the Securities and Exchange Commission and the National Labor Relations Board; and severely restricts the work of those and other regulatory agencies, like the Consumer Products Safety Commission, the Mine Safety and Health Administration, the Occupational Safety and Health Administration, the Federal Communications Commission. Untempered by precedent, originalism would require reversing Brown v. Board of Education, the principle of one person-one vote and landmark cases guaranteeing the right to free speech.

Scary stuff! And these folks are appointed for life?
