LMA – You didn’t answer my question.
Anyway, I don’t recall the Medrash about Avrohom Aveinu talking about Boel Aramis, I remember just about the Bris part, not anything more -are you sure?
“The prohibition of Arayos is the foundation of our connection with Hashem. This is precisely why Bilam Harasha advised Mo’av specificly to be machshil Klal Yisroel through Arayos. As the posuk states “V’Ra’ah Bicha Ervas Davar V’shuv Mei’acharecha”.”
While what you wrote is true, I don’t think Klal Yisroel would have been destroyed by just being Mezaneh. (It’s only a D’Rabbonim.) That is why the Moavite women always took out their Avodah Zorah and said you must do this also and they did!
