knacker: there are many things that chassdim do that most other observant jews consider to be aveiros. making kiddush this way is counted among them. if someone would do that in our shul we would tell him he is not yotzei kiddush.
i heard that the satmar rebbe used to be mchalel shabbos after shkia until asked otherwise by rav kutler. if this story is true then the satmar rebbe would be considered a mechalel shabbos according to other torah jews. i am not chas veshalov trying to belittle chassidim, gd knows there are things about them we all should learn but facts are facts.
i dont think you can call crazybrit an antisemite for suggesting that many things that the chassidim do are neged halocho according to everyone else.
I’m going to be Moche on behalf of the Chassidim. You may be correct that there are certain shittos that Chassidim hold that are not universally accepted (such as Davening and doing Melacha after Shkia), but they have whom to be Somech on (such as Rabbanu Tam and the Taz). If you are being Motze La’az on those who follow their shittos, you are being Motze La’az on those who created them. Your beef is not with Chassidim, but with Rabbanu Tam.
That being said, I agree that just because Chassidim hold of a shitta doesn’t mean that others need hold of it as well. He may be Yotze (you have no standing telling him he isn’t), but you shouldn’t be Yotze with his Kiddush (as has happened to me many times).
