Humans are animals, so yes, we are equivalent to animals, because we are animals. Can you explain what makes humans more precious than other animals, is it out ability to mass murder, destroy the world? because honestly humans are ruining the world, so what makes them so precious? You also realise animals have "a irreplaceable and unique set of genetics" too? that's not just reserved for the wonderful precious humans by the way.
Oh yeah, how can you compare taking a pill to remove some unwanted cells from your body (early stages) to hanging an animal upside down, slitting their throat, and leaving them like that until they're drained of blood, only then to go and chop up their body to eat! What a weird comparison right, obviously the first is the worst!
The fetus is not a human, only has the potential to be, I don't know how you can disagree with that. You actually can eradicate a fetus from your body, that's what abortion is. Yes later stage abortion is more of a complicated topic as the the procedure is more dangerous and doctors know that, that is why late stage abortions are not given out very often, and are often used when the mothers life is at risk. Most people that are pregnant and don't want to be will have had an abortion way before it gets to the "later stages" so imo that is a pretty irrelevant argument against abortion as it most definitely isn't the most common abortion method.
You know what else is gut wrenching and disgusting? when women had to go to people who carried out abortions in their homes, without anesthetic, often with serious complications, thousands of women died every year because of this, as they couldn't see a doctor for the complications because they would be put in prison since abortion was illegal. If they couldn't go to someone else (as that often cost thousands, back in the 60s and before) they would do it themselves, using coat-hangers/ any object they think would work. You know why? Because back then, the men in charge decided that they can police what women* do with their bodies, this resulted in thousands of deaths. So legal abortion is 100% a good thing, it stops things like this happening.
