RSO, to be fair to the previous lubavitch poster he may be making an argument made recently in a sefer about moshiach (which is admitted by the author to be a chiddush) regarding that gemara that there are reasons to say they continued after the death of the teacher. its making the rounds in lubavitch right now. I personally dont buy that chiddush but its based on a svara which was not explained in the previous post.
I dont think its fair to say everything is based on misinformation. Sometimes people make bad arguments, or refer to things in short hand or make arguments which are presented as fact but are just one of many opinions. Many nonlubavitchers do similar things and have done so in this thread. Some people just dont make good arguments. Some have different opinions from each other. It wouldnt be right if i said all nonlubavitch opinion is wrong because i heard a few people make bad arguments. What are afew examples of blatant misinterpretations of chazal?
Also if a gadol byisroel says something it has a level of credence. If the chazan ish said a pshat in rambam that i thought was wrong and someone told me he said it i actually WOULD consider that evidence and i wouldnt dismiss him out of hand. He knows what he is doing after all. But again nobody here is saying cause the rebbe said it in a sicha therefore its correct, i said to look into the sichas so that 1. you dont think this all came from chassidim but from their leader 2. you see if the svaras make sense to you, but you cant dismiss something as nonsense before hearing the case for it. Sometimes things arent as they appear at first, and it takes someone who knows the sugya to raise a good question and then bring a chiddush that resolves it. Plenty of instances in torah like this.
