Senator Rick Santorum, the Republican of Pennsylvania, is ignoring calls that he apologize and resign from his Senate leadership post for comments he made comparing homosexuality to bigamy, polygamy, incest and adultery. Santorum’s remarks came as he talked about the Supreme Court reviewing the sodomy laws in Texas. He told the Associated Press, “If the Supreme Court says that you have the right to consensual (gay) sex within your home, then you have the right to bigamy, you have the right to polygamy, you have the right to incest, you have the right to adultery. You have the right to anything.”
