There is no pro-abortion people, that is a moronic term invented by the right wing members of the fertility cult!
There are pro-choice people who believe that a woman should have the right to choose and the reasons for that are many.
With the type of radical right wing stupidity we now see the women will soon be employing coat hangers or other sharp implements instead of Doctors to try and intervene in an unwanted pregnancy.
While a fetus has no mental activity it is worshiped by some elements of society which also lack mental activity and if you want Atkins, Ryan, Romney and their ilk to set social standards I can only say: It is a small setback for an individual but a giant failure of civilization!
