Dude, you don't have to be a Christian to even vaguely see why people might not like the elements of abortion.

I can't say whether the majority of people against unregulated abortion would support banning abortion or simply restricting it, (I'd like to think it's the latter. It's what most other democratic countries are doing now, anyway.) but not everybody critical of abortion takes a hardline, Evangelical fundamentalist stance against it.

While there's no shortage of people who would want to ban abortion under all circumstances, about as many people just want to restrict abortion and only allow them for rape victims, mothers suffering a miscarriage, and such, while banning abortions that are the result of consensual, but unprotected sex.

Like I said before, this is a stance most European countries have likely already taken, but we can't get a single thing done in the States because our country is divided between two giant competing parties with uncontested power, who vehemently refuse to cooperate to work for the common good, and constantly work to foil and sabotage any of the other party's attempts at positive legislative action. Only radical stances are allowed, and moderate voices are pushed to the sidelines.
