My reading was being charitable, but I was corrected by the follow up. I wanted to believe this person understood the top level comment was venting and asked anyways (implying sarcasm) because that seems like a pretty basic inference from most people's social experiences. But instead they clarified they (and I guess you as well) truly do not realize that the top level comment is upset because prenatal tests were part of a traumatic event. You apparently did not realize the top level comment is not conflating a false positive and a false negative, or solely blaming prenatal tests, but rather they're saying all forms of inaccuracy in a prenatal test have great potential to cause heartbreak... which is 100% true. tl;dr: Their comment is venting about something unimaginably painful while staying on topic and closing with a relevant statement, so I REALLY don't get what the point of drilling into the more personal part of it buys you? _ I also assumed you and the other reply did not un-sarcastically try to ask a stranger if they regret not aborting their child so casually. But again, I stand corrected.
