to Daas Yochid: I did not say anything about the letter- on the contrary, the RCA is fully competent to point out what they think is wrong. My point was that you did NOT have necessarily have to listen to Rav Ovadia Josef in this matter. Whether to support Rav Stav or not is not a halachic matter. If you follow Rav Ovadia Josef. then you listen to him but others (RCA, Rav Druckman and others) can certainly argue with that view.I tend to agree with you that the language was very intemperate.
To Popa bar abba; Halacha is encapsulated in the Shulchan Aruch. How to conduct your life as a jew is hazier (must you wear a black hat? Must I follow my view as to drafting all jews ?) I do not agree with you that the Rabbonim konw all the time what would be the Torah way. Do you follow the way of RSR Hirsch? Or, do you follow the way of the Hungarian rabbonim (firmly against limudei chol)?Do you follow the way of Rav Kook or do you follow the way of the Neturei Karta? The mishneh says “ashe lecho rav”- you can choose who your mentor is. Allow every Jew to have that choice and do not denigrate others who do not view the world as you do.
