ujm,
“Avram: Isn’t that a No True Scotsman?”
Yes, it could be. However, I think that the left and right within MO are heading towards a schism. The open-orthodox have already started the process, giving their movement a unique name and establishing separate communal infrastructures. Some clear lines in the sand have been drawn, though some will say not clear enough. Given that, I think there’s legitimacy to a MO person declaring that someone holding certain OO “shittos” are outside the bounds of MO.
“That would be similar, perhaps, to Ultra-Orthodox excluding ganovim and molesters from their own definition of Ultra-Orthodox.”
So similar to what I wrote to Gadolhadofi, I think there’s a difference between those within a group who fail as people, and questions about the shittos a group holds. This debate is not making those differences clear at all.
