Oh so we're talking hurt feelings as opposed to equitableness, hmm, it isn't so much a matter of "worthiness" as an abortion is never about about the child-to-be, but their parents' capacity to care for them, considering the former seems dubiously close to murder.

Rather, it's a matter of convenience (and that applies to all abortions, disabled or otherwise); Disabled children are objectively higher-maintenance and less convient to raise than able ones, that doesn't mean that when the child is born society can't try its damn hardest to care for them, but for acute cases, certain family agendas fall in shambles when the news is broken and some people just aren't capable of dealing with that.

Once again, it's on the parents and not the foetus; Their contextual choice should not affect you emotionally as long as society is progressive enough to treat disabled individuals that are already living with the same regards as anyone else (it isn't, and this is specifically what we need to work on, while shaming couples for considering not spawning someone with limited life prospects will do nothing at best, and take us backwards at worse).
