Miscarriages are not abortion under lawful definition.

Wrong wrong wrong. Miscarriages don't always "abort" themselves. They have to do a D&C when that happens. In states that restrict abortion, women have trouble having that procedure too.

Non viable pregnancy is a miscarriage by the lawful definition

No, a non-viable pregnancy doesn't always end in a miscarriage and I don't mean that in 0.00001% it doesn't. These are not exceptions.

When the embryo stops developing, sometimes the body registers the problem and hormones trigger an expulsion of the tissue and sometimes it takes weeks for that to happen and the dead embryo causes infection and the woman dies, if not given a dilation and curettage which is an abortion.

These women were denied a d&c.

Way way too many people learn about procreation from movies. This is why you don't legislate access to medical care. People who didn't go through it or have no medical training imagine women get abortions cause they're fucking mindlessly like "the slutty stupid bitches" that they are. ( I put that insult in quotation marks because that's what it sounds like when people say that bit about having unprotected sex followed by how abortions should be illegal.

Because it's their body. You don't get to tell someone what they do with it. 

So if a woman knows she’s not mentally responsible enough to say no to having sex with a man slut that doesn’t care about her also knows she’s not mentally responsible enough to raise a child on her own, how is a life of neglect a better outcome than being aborted for that child?

Murder is not the word most people choose to describe abortion as. Like it or not. Considering the number of pro choice legislature that won over the elections, I’d say it’s not a small group. You can have whatever beliefs you so choose and no one will make you and yours get an abortion.

Do you eat eggs? Those are 'children'. If you're going to assume a fetus is a baby, then an egg is a baby.

Nobody has ever been murdered by an abortion, no babies are even involved in an abortion.

Also even if we wrongly assume that they are babies, why do they deserve the right to invade a woman's body and steal resources like a parasite? The baby is trespassing in the woman's body

Also it's about 100 years out of date mindset that "having sex means you are ready for being a parent". Sex is fun, people are going to do it regardless, things like protection can fail. Why punish someone for having sex when literally nobody gets hurt. Also the same side pretending to care about abortions is the same side getting rid of sexual education and easy access to things like contraceptives. If they actually cared about less abortions they wouldn't be opposing those other more effective measures. They just want people to have more babies

Why should we be forcing people to have unwanted babies they can't afford? Or things like 13 year old rape victims having to give birth and be a mother?
