I'm an Italian noahide.
Through the link
I read the article "Judaism and Homosexuality: An Alternate Rabbinic View ", written by the English Orthodox rabbi Chaim Rapoport. On the third page of the text Rabbi Rapoport states that, according to the authoritative Posek Rabbi Moshe Feinstein, lesbian relations are not forbidden to Gentiles women. Rabbi Rapoport cites as source the text "Dibberot Moshe on Shabbat vol. 2 (New York, 1971), ch. 59, section 34 ". I have tried to find this work, without success, nor have I been able to find any further evidence regarding this halachic position of Rabbi Feinstein. I contacted Rabbi Rapoport asking him the courtesy to give me further information on the matter, but he did not reply.
Can you help me know the aforementioned source "Dibberot Moshe on Shabbat vol. 2 (New York, 1971), ch. 59, section 34", and more generally to understand if is correct Rabbi Rapoport's statement about the position taken on the subject by Rabbi Feinstein correct?
Thank you very much
