“That’s like quoting the failed messiah site as proof for something I don’t like in the Chareidi world.”
I thought it would be too, but if you take a look at the site it’s really not anything like failed messiah. Also, scroll to the bottom. They have a disclaimer saying that Lubavitchers will react to it exactly as you just did.
Toi, you aren’t going to see me giving you any sources to help the Chabad side because I’m fervently against Chabad Meshichism. There ARE contemporary sources (eg. Rav Shach, Rav Belsky) that one could use against Chabad, but the site you reference leaves them out. They use old sources, and bring them down in the case of Chabad themselves. Why should I care how an anonymous internet website paskens? If they don’t bring down contemporary sources then their halachah section is no better than the Chabadniks here not giving any sources.
We’ll go around for circles forever here. We’ll ask the Chabadniks for sources other than the Rebbe; they will not provide. Why? Because they proudly have a concept of being “bittul to the Rebbe,” meaning they consider it a good thing to learn only the Rebbe’s shittahs. It has always been our way to learn all the shittas, even the ones we by which we don’t hold; that’s how the gemarra was written. How Lubavitchers can claim that it’s a bad thing to learn outside sources is beyond all logic.
