The same applies when Americans come to Israel for yomtov and make minyanim as if they were in America
Sorry onlysheker, but this is very wrong. R’ Shlomo Zalman zt”l was vehemently against people doing things outwardly in public which was not inline with what the Israelis were doing (e.g. He did not allow eating in the succah on shmini ateres, Kohanim singing in duchaning during second day yom tov). Nowhere does anyone with daas torah say you don’t make a minyan. Even in Kol Torah (R’ Shlomo Zalman’s Yeshiva) the Americans made a minyan for their Yom Tov.
As for the kriah being a communial obligation, if there are a minyan of people who need to hear Behaalotcha, is that not their communal obligation.
Furthermore, it is a slap in the face to the people of Israel when this is done.
No, it isn’t. Putting tfillin on at the Kotel during chol hamoed is a slap in the face to the Israelis. How is being nahug 2nd day yom tov a slap in the face? Please don’t tell me you mistakenly hold that when in Israel you automatically hold 1 day. Also please don’t give me the false psak that you need to put on tfillin during 8th day of pesach if in Israel.
How fitting that in Olam HaShakker someone with your name comes and says something so distant from the truth
