So you would question a woman's ideology if she did not believe in abortion or the right to choose, but only in 'God's will', she then miscarries her fetus, tells herself it is okay since it is 'God's will'... but then reacts negatively when shown an image of 'God's will' in the form of her miscarried fetus? By your argument, she shouldn't be reacting to it either because the miscarriage is a product of 'God's will'.
My mother is pro-choice, but also a Catholic, something she attempts to reconcile with herself quite often. But she virtually becomes faint at the sight of blood.. any blood.. And yes, if she were shown an image of an aborted fetus, she would probably react very negatively. Not because she doesn't want to see 'dead babies', but the mere sight of blood makes her feel like she's going to pass out cold.
I edited the threads in which you posted those images. Whether pro-choice people react to them or not, you are missing one important thing. Not everyone likes the sight of blood. You may think that because many support the right for the woman to choose and/or they don't think the fetus is 'alive' as you and I are alive or a newborn baby is alive, does not mean they are able to look at the blood and guts..
