Rav Abadi's Psakim

I was wondering whose Rav Abadi’s audience was when he answered questions in kashrus, taharas hamishpacha, etc.? Was he answering for Ashkenaim, Sepharadim, both, other, etc. ? How did he feel about these distinctions in Judaism? I know very little about Rav Abadi except that he is a talmid chacham.

Baruch Hashem Rav Abadi continues to answer, and as you say, his audience is an amalgam of Torah Jewry.
The Rav gained prominence as the Posek of the Lakewood Yeshiva (BMG) some many years ago and would answer the Halacha questions of the predominantly Ashkenazic student body. Of course being of Sephardic origins, many sephardic kehillas were drawn to him as well. With further prominence he would field questions from literally around the globe from all and any type of kehila.

Specifically to answer your question vis a vis Halacha, it is well known that there are differing customs for Ashkenazim and Sephardim. As an overview in a simplistic sense the Shulchan Aruch was written by a Sephardic sage, The Bet Yosef. At the same time the Rama (Rav Moshe Isserles) was compiling his own Shulchan Aruch and upon publication of the first, set aside his and instead amended the Shulchan Aruch of the Bet Yosef, in cases where the Ashkenazic custom differed. This became the “Code of Jewish Law” as is accepted today. Having said that later day Posekim have after studying the source material at times ruled differently than the Shulchan Aruch. By the same token a Posek may sometimes rule that a Sephardic jew should or could follow the Ashkenazic view and vica versa.
Rav Abadi as well, has at times blurred this line in his rulings to his questioners. That is the essence of a Posek. There are many dimensions and aspects that the Rav considers before answering, but generally he will pasken for Ashkenazim/Sephardim in accordance with their respective minhagim.

I hope that answers your question.
