As I mentioned in a comment, I had never seen or heard the term SNAG until reading it in this thread. It is not a derogatory term uttered aloud in the OOT communities I’ve lived in. In about 7 decades of life Misnagid has only been used as self description and see when reading Jewish history.
Never has local Chabad used the term aloud I. My presence.
As I have repeatedly commented: in small OOT communities all types of Jews support all Jewish institutions. Since the Chabad Day School is majority funded by both Litvish and non-orthodox Jews, the local Chabad would not public use those terms about their donors.
The true infighting that I see, hear abc read about is I. The major Jewish communities and EY
I grew up in New Haven. I think we belonged to (and paid dues each year) to 4 shuls. I left for another CT Town 35 years ago , but still belong and pay dues to 2 of those that are still operational.
My big city Jewish friends did/do not understand the obligation small town Jews take upon themselves to make sure all Jewish communal organizations can survive and fund them.
Federation makes Chabad, Litvish and Solomon Schecter schools all constituent agencies and allocated funding. Thus wealthy Reform Hews knowingly fund Orthodox education through Federation donations as well as responding to individual fundraising.
As I said we self identified as Misnagid, but that doesn’t mean that there isn’t a bronze plaque with our family name on a classroom at THS Chabad Day School. I also spent two years as President of a shul which because of mergers davened Nusach Ari using Tehillay HaShem sidfurim
