Yuh. If a woman gets an abortion, it's contagious and she gives abortion-itis to every other woman she comes into contact with.
You missed the point. Consider everything including the effect of the unvaccinated spreading the virus (which you pointed out to), the effect they have because the unvaccinated take more beds in hospitals, and even if you want to argue they prolong the pandemic (which I don’t agree with, but let’s even assume that too). With all those together, if you were to somehow translate that to the number of life losses per unvaccinated person, it’ll be much less than 1. On the other hand, for each abortion, 1 life is lost.
To be clear, I’m prochoice both for vaccination and abortion. This argument isn’t made to say something negative about abortion.
Ps. The vaccines certainly help a lot in preventing covid hospitalization. But are fully vaccinated people (with 2 doses) much less likely to get Omicron or spread it? You might want to look at recent data.
