No idea if your first part was directed at me, so I'll respond to the point that I think is directed at me.
I have to say though that the DNA argument does work to an extent. There are genetic differences between the DNA of a zygote and the DNA in your skin. Different genes have been switched on and off and thus you can see the cells that are formed after conception are distinct from the specialized cells of a fully developed human. After all if you cut off your finger the cells in it cant suddenly grow into a human can they? But the cells of an embryo can. The argument thus has merit, and is a valid opinion.
Bolded: That's not exactly true, in fact you can use those cells from cutting off your finger to clone a new life.
We can't just go off the definition of human life because it opens up a whole slew of things, that's why it's important to decide when human person hood begins.
LoneJedi: You haven't answered the question, and you're being presumptuous again. There's no basis to the claim that woman are getting abortions because they simple are just sleeping around. The inconvenience factor could come from a variety of different issues.
They're to young, not enough money to raise a child well, would rather raise a child in a two parent house hold. ect.
The link you provided shows that as well.
woman of the age 20-24 are likely to have abortions (college age girls) and teenagers below the age of 15 high school aged girls. One of the highest statistics of a woman's income is lower then 15,000, that's not enough to care for a child. Then you have the maternal status, a high majority of woman are not married when they get an abortion which could simply mean they want the child to have a father and not live in a single parent household. Combine all these together simply put woman get abortions because they're thinking logically and realizing it's best to not have the child then to have it.
edit: no one has really made a case that aborting is murder, so in other words pro-choicer advocates are just forcing their morals on the rest of society.
