The 9/11 hijackers were not motivated in reaction to judicial activism that eroded the Constitutionally guaranteed right to life.
They were motivated by a desire to destroy all vestiges of the Constitution, not just the now-attenuated right to life.
Oh, I see--if one has the "correct" motivation, shooting an abortion doc in a parking lot until he stops moving is all right with you, or at least enough to get him off on criminal charges.
