You asked a specific question that was way outside of the gray zone… suggesting that she does not care about halacha.
I didn’t read the question that way. To me, he was asking whether there would be any scenarios today which would constitute Mesirah, not whether she believes the Torah came down including a parshah of Mesirah. There is plenty mokom to say that nowadays Mesirah is no longer an issue – or at least, is not as chomur as it ever was. Not because the Torah changed, but because the legal system has changed.
