Wolves eat other animals, but they don't eat wolf.

But many species kill their young after birth, including primates such as chimpanzees.

Are you taking the cannibal position?

Not at all, only that to hold any form of life sacred despite the lack of development should be universal, if that's the position a person wants to take. No doubt many who would be against abortion would happily be pro-war, pro-execution and indeed pro-carnivore. Or they would otherwise be critical of population growth, etc. pro-lifers care little for animal life they eat. So to refer to abortion as murder, one would have to condone one type of murder over another, this a level of hypocrisy would be present.

Abortion was approved with the intention of targeting demographics of minority groups.

Perhaps in America, but not world wide. Abortion tends to be prohibited in primarily orthodox religious areas like Ireland and areas of the middle east where Muslims fuck goats. Abortion in the UK tends to be conducted by the Marie Stopes charity, she was a British campaigner for women's rights. Nothing to do with reducing population of minorities.

The legal justification for abortion is that US citizens

Again, the world is far wider than just the US, and not all the world must adhere to the same cultural norms or definitions. It is easy for the US to forget that places like Europe have more widely normalised tolerance for those who are not devoutly religious and not so bound to such a recent history of slavery as an example for one's moral compass.

Frankly, there are too many humans, and too many stupid humans. The idea that all idiots must go around worshipping a blob of jelly is as ludicrous as calling masturbation genocide.
