Plus it seems weird to pin a point of ethics to a moving target: do abortions which were previously ethical become retrospectively unethical as medical technology improves?

And in a tangentially related vein, I've always been bemused by the hyprocisy of people who are adamant that abortion is murder, an absolute evil that must be stopped at all costs... oh, wait, except in cases of rape or incest where apparently those fetuses are not deserving of protection.
