The left: We don't believe a zygote or embryo is a human being.
Also the left: We support a woman's right to choose whether or not to have an abortion (but we want to reduce the abortion rate of zygotes)
Me: If you believe that zygotes aren't people, why would you care what the abortion rate of zygotes is? If I kill a pig for meat, nobody (except vegeterians and vegans) cares about how many animals get killed for food, because it's viewed by the majority that farm animals aren't human. If you REALLY believe a zygote or even an embryo isn't a human being, why would you want to reduce the rate at which they get killed? They aren't human after all, so it shouldn't matter how often they get killed. Collect stats on it if you want for data's sake, but don't advocate for reducing the death rate of something you think is just a clump of cells.
The right is consistent on this front. They believe a zygote is a human being so they want less of them killed. You can agree or disagree with that, but it's worth respect. The left isn't being consistent. They want to reduce the death rate of zygotes but they don't believe zygotes are human beings, so why aim to reduce the death rate of zygotes?
