“The velt has accepted Rav Moshe’s Psak on abortion.”
If by velt you mean you personally, then you MIGHT be correct (I doubt you’re even correct on that see insult thread).
If you mean the Frum society, then you are completely incorrect.
Granted I cant convince you, since you havent encountered anyone in such a situation but here is some food for thought:
Pick up ANY medical halacha sefer, they all go on a long arichus on the subject. Obviously every individual case needs to be judged individually. (always true but especially here). If you really think in practice “the velt” follows R’ Moshe why does every modern sefer eg R” Zilbershtein, R’ Asher Weiss all still discuss it? These are practical halachik teshuvos, not stam l’hagdil Torah. R’ Moshe was nifter over 30 years ago. If you are right Any modern shaeila on abortion should be: ” Already paskened see Ig”m”
