I heard again, on a morning news cable show, the term "religious liberty." As anyone with half a brain knows, this is a euphemism (worthy of the wily wordsmith Frank Luntz) that really means "religious bigotry." Republicans and social conservatives don't want to admit they are religious bigots.
To be a champion for "religious liberty" sounds so much better than calling yourself what you really are: A bigot who passionately dislikes gay people and wants to curtail their rights as U.S. citizens.
