Pro-lifers threaten to murder pro-life Congressman, his children and grandchildren, for pro-life Congressman's failure to be sufficiently pro-life. And this detail leaps out for it's cruelty...

Toward the end, the letter, signed "The Devil within Us," says this fate can be avoided if Stupak resigns immediately and admits that his health care vote "was wrong and under handed," or if he follows "in the footsteps" of his late son, Bart Stupak Jr., who committed suicide in 2000.

Stay classy, pro-lifers.
