@EchadHaemes I don’t think Rav Schneersons Torah and Hashkafah have any more relevance to non-Chabad than they did before. It’s important to learn, sure, but the Hashkafa isn’t something a Litvak or Chussid would put above their own Rebbe or Rosh Yeshiva. And everyone learns their Rav or Rebbe’s Torah as first and foremost with all the others being a lower priority. Like a Satmarer learns Divrei Yoel and sifrei Chassidus, an American Litvak would prioritize Pachad Yitzchok. Then if there’s time or interest, may pick up his seforim on the RAMBAM or read a sicha or two. Likutei Iggros are all but ignored outside of Chabad.
I don’t see why a couple of frum Internet influencers mentioning some Chabad holiday really means much, especially considering the vast overrepresentation Chabad has on the ‘net.
