Look, I'm not making a morality judgement here, but this is greatly oversimplifying things. Fetuses are considered generally viable outside the womb at 24 weeks (5.5 months).
This abortion occurred at 7 months. This could have been a person if labor was induced or a c-section had been performed at the time instead of an abortion. I have a hard time believing that doesn't or shouldn't have an effect on the discussion.
Hard line, single sentence takes like yours or the comment you were responding to help no one. They offer no room for nuance, for consideration of unique situations, to fit in with the complex reality we all live in. They can't convince anyone on the other side and don't further depth of thought in those in agreement.
They offer a cheap dopemine hit for people already in agreement with you, further encourage polarization of opinions, and general tribalism. It's useless preaching to the choir that only further entrenches hardline stances and decreases the likelyhood for discussion, compromise, or anything vital to surviving and interacting with others in reality.
Again, not making a judgement on fetuses, personhood, or abortion one way or another. My partner was born at 6 months and given up for adoption. Conversely I have a close friend who got pregnant from a one night stand nearly a decade ago, decided to keep it despite that being quite possibly the worst choice for her at the time, and her life has been in the shitter since with no signs towards improvement. I see both sides of this.
I just refuse the idea that anything as complicated as the question of "When does personhood begin?" can be broken down into asinine hot takes by either side.
