“70 facets of the Torah” does not mean that in every issue there will always be various acceptable opinions. There is always an ebb and flow of arguments which diversify and are eventually unified. Just like Shammi and Hillel and their students respectively were great scholars and holy people, does not mean we say “shivim panim latorah, and I choose to follow beis shammai” and the same can be said for many machlokesin throughout all of Jewish history. The fact is that The Baal Shem Tov, the Maggid, and some (if not all) of their successors believed that Chassidus is THE WAY not A WAY, and the ideal derech for klal yisroel and all Jews is Chassidus. The Baal Hatanya and his successors believed this and went to great length to spread Chassidus as widely as possible.
Most of the arguments being advanced by “litvisherchossid” are the very same arguments which were made against the Besht, and against the Maggid, and against every rebbe and group of chassidim who showed up in any town in Europe. You are reiterating two hundred year old arguments of holy misnagdim, and unholy maskilim. That is certainly your right, but let us not play pretend like Lubavitcher chassidim suddenly started to act in a certain way.
You never heard of people looking in to yichus? You never heard of people wanting to marry people with similar life experiences and upbringing? You think rabbinical hierarchies don’t exist in the world? You think other Jews don’t think certain issues are core to religion and are correct to the exclusion of others opinions? You don’t know Jews who hold that the yeshiva/kollel lifestyle is a chiyuv? Don’t know anyone who says Zionism is assur? Kanois is mandatory? You have to serve in the Israeli army because it’s a mitzvah? There are all sorts of hashkafos and halachic opinions that are propagated by rabbonim as being a chiyuv on all Jews. So Chabad holds that a person has to learn Chabad chassidus.
Get your head out of the sand man. L’chaim!
