Hi, pro-choice mathematician who’s done biology work here. Fetuses are alive. Fetuses are composed of living tissues. If a fetus was not alive, it wouldn’t grow. If a fetus doesn’t grow it can’t be born. You will never win an argument with an anti-abortion nutjob if you get basic facts wrong. The reason a fetus doesn’t have the same moral weight as the human it needs to live off of is because fetuses aren’t sapient.
