I think we need to pick our battles. Plan B does not cause an abortion - it's a contraception that prevents ovulation and does not affect a woman with an already-fertilized egg.

I am not sure if that is true. I believe that it also modifies the uterine lining to prevent implantation of an already fertilized ovum.

However you contradict yourself. In Post 16 you quoted the University of Illinois at Urbana-Champaign in saying Plan B "may inhibit implantation by altering the lining of the uterus".

This causes the embryo to be aborted.
