I am the mother of shluchim in remote places. You explained the fighting over control in 770 very well – but I will add, a huge part of the problem is the “rules” of the game. Imagine playing football against a team who moves the goalposts, ignores the referee and makes up its own rules as it goes along, so they change almost daily. The one constant is, there ARE no rules. Anything the team does, including violence, is perfectly respectable & even encouraged.
This sums up the Moshichisten AKA Talibanisten. They are in the minority but they are funded by a couple of very wealthy men (one who offers every bachur a new hat & suit for Pesach IF he says Yechi!!) and some wacked out Rabbonim here & there. So they continue. The other team follows the Rebbe’s directives, which are very clear, which the Moshichisten don’t do. Don’t confuse these thugs with the facts. Oh & one other thing… most, if not all, never saw the Rebbe or listened to a sicha or maamer. Or even learned anything. They have no idea how it felt to see the Rebbe b’guf and the impact even just a look has on your neshama. I have had my own personal nissim from the Rebbe .
