I could not say the number of times I’ve heard 100% pro-life politicians, like Rick Santorum, called “extreme” in their abortion view by the mainstream media. I do not recall one time when a 100% pro-choice politician, like Barack Obama, was called “extreme” by the same media.
Rick Santorum believes abortion should be illegal for anyone, for any reason, at any time. Barack Obama believes abortion should be legal for anyone, for any reason, at any time. In the logic of a spectrum, if one end is to be labeled extreme, the opposite end must also be extreme.
