A person does not have to be a Christian to have this belief. In my opinion, it'd be wrong even if God had not said so. Personally, I describe myself as 'pro-life, with an asterisk'- meaning, there are some situations in which it is not necessarily wrong. However, what irks me most on the subject is the way it's presented- and the changes in the way it's been presented ever since Roe v. Wade. Currently it's the 'women's own bodies' and 'women's health care' excuses, and neither are valid. An unborn child is not 'the woman's own body,' and abortion has nothing to do with 'health care' unless the woman's life in is jeopardy.
