BBO: “I take issue with that outlook on yiddishkeit. I may have a very holy and ancient minhag to not keep shabbos, but as long as i keep it in the realm of MINHAG and don’t bluff that it has a halachik and legal basis, then im alright?!”
There is a difference between shev v’al taaseh and kum va’asei. Not keeping Shabbos is kum va’asei and no minhag can allow actual chilul. But if there was, say, as minhag not to make eat cholent then that would be ok. Same here. If there is a minhag not to sleep in a sukkah I would find that ok.
However, having said that, I do understand your objection. It’s just that I don’t object in the same way.
