^ surprised the mods let that nivul peh through the system.
Anyway, Chazal argued with each other all the time bizman hagemara. Rambam and Raavad disagreed on nearly everything. The Rema’s minhagim differed from the beis yosef’s, but we still value and treasure both- they are mamash on the same page!! Many respectable rabbonim burned moreh nevuchim- are they apikorsim for disagreeing with rambam? Vilna Gaon said Rambam was very misguided. He also put all chassidic rebbes in cherem.
My point is, arguing and challenging are integral parts of Judaism and the halachic system. When we stop arguing and challenging, we will eventually stop coming up with chiddushim and new ways of applying age-old wisdom to our own times. However, all arguing must be done in the spirit of ‘machlokes l’lsheim shomayim.’ regarding the shelo asani beracha, most of the people arguing for its removal are certainly not arguing l’shem shomayim. However, they haven’t violated any of the ikkarei emunah, so what is the havah aminah for saying they are apikorsim? There are girsos that have one beracha as she’asani yisrael, and several poskim even rule you should say that one beracha, which will allow you to not say the other ones, which could be levatalah. With that much confusion, you cannot go outright and call them apikorsim
