Pointing out serious issues with a group isn’t sinas chinam, the same way the pointing out serious issues with Messianic Judaism isn;t hatred. In fact, most Lubavitchers today are tinokos shenishbu, unable to see beyond the cult they were born into, and unable to read the ikrei emunah of the Rambam and realize how many are being violated regularly. I love them all, even as I am pained by their behavior. They are very similar to Lev Tahor followers or followers of Eliezer Berland.
you, however, are able to look at the ikrei emunah of the Rambam and see for yourself that
1. Hashem alone runs the world, not in partnership with any Rebbe
2. Hashem alone lives forever
3. Hashem has no physical form, so you can’t say atzmus melubash baguf
4. You are only allowed to Daven to Hashem, nobody else
5. If a person claiming to be moshiach dies, that’s it for his candidacy. Quoting gemaras about Yaakov Avinu lo meis or similar doesn’t change the fact that in metzius, the Rebbe was niftar and got buried 25 years ago.
6. If someone claims to be a navi and makes multiple false prophecies about when moshiach is coming (a good prophecy), then that person is a navi sheker. Not hatred, halacha.
Like I said, they have forced and krum terutzim, and can fool regular people. But that’s why we have gedolim, who can tell you not to listen to forced and krum teirutzim. That’s why you need to listen to mesorah. There’s a reason the Gra refused to meet with the Baal Hatanya.
Don’t listen to me, maybe I’m just a krum snag hater. Listen to your gedolim, follow your mesorah.
