Takes-2 a meschichist isn’t a ra’ayah”
Why are you bringing up Meshichists? Chabad has sent shluchim there way before Meshichist movement came about.
Also, in the rebbes mind its an inyan of saving neshomos, that would have been eternal lost.
No doubt it overides minyan, no less than all yiden who liven in ‘Kefarim’ all year long and only came in for Rosh hashanah, megilah etc. becuase of Parnasah..
