To QWERTY- obnoxious people don’t learn that from Judaism, ie if someone is only Chabad because he thinks no one else has value other than Chabad, he is definitely lacking in ahavas Yisrael and has blemished his own Neshama (see derech mitzvosecha of the
Tzemach Tzedek Mitzvas ahavas Yisrael.)
People like this aren’t unique to Chabad…
And I do my best to have no part of such mindset/ behavior. It really comes from a lack of self esteem.
