It is right to discriminate against wrongful behavior. The Lord himself discriminates against behavior. The United States and every nation must decide what behaviors they wish to accept into their society as morally just. There is no way to separate government and morality. We discriminate against those who commit murder, theft, and a host of other issues. Even if these people insist that it is their right to steal or murder, we deny them that so-called right. The principles we stand on define our society.
