"American slavery was sickening. Having babies isn't. Freeing blacks was NOT sickening. Killing babies is"
Abortion isn't killing babies
"...don't use something like slavery where freeing people from it was a good thing that only selfish slave owners would've found opposition to"
The Bible allows for slavery, so why is freeing people from slavery a good thing?
"Abortion had to be politically manipulated into our minds to even sound sane"
No it didn't
"Because people will support anything claiming to be "human rights." "
No they won't. If somebody said that killing nonbelievers is a human right because it's part of their religion, you wouldn't see a bunch of people scrambling to support that and say they should have that right.
"This argument shows you don't know much about how the abortion process works"
I bet I know more than you do, because you're the one who thinks an embryo is a baby, when it's not
"Matter of fact, abortion doctors force mothers to look away from ultrasounds during abortions because mothers will often change their mind if they just see the baby (not even see it getting attacked; seeing it get attacked and seeing the baby fight for his life is what turned one up-and-coming big name in the abortion industry into a staunch pro-lifer)"
Do you have any evidence for this claim? I'm pretty sure they can't force someone to not look at the monitor, assuming they could even see the monitor from where they are in the first place.
A baby doesn't "fight for its life" during an abortion procedure. It has no mental capacity to understand what's going on.
Are you talking about Abby Johnson? Because her story about being shocked by an abortion she supposedly witnessed can't be confirmed with facts. The story she gives doesn't match with what we know happened. Also, she's a known liar, like so many anti-abortion activists.
"Pro-life has little to do with religion"
Really? So it's just a big coincidence that more religious people tend to be more opposed to abortion?
"Abortion wasn't much of a concept well after atheism was introduced to the public in the mid-1800s"
I'm not even sure what that is supposed to mean. Atheism was not "introduced to the public". It has been around for thousands of years.
"But I stand by the idea of killing is wrong, and I would still stand by that whether I was religious or not"
So when god commands the killing of people in the Bible, is that wrong?
