> it is morally acceptable to choose to cease associating with someone over incommensurable views
For you? A lot of situations are morally acceptable. For you to demand others to do it, even though they clearly not inclined to? Very narrow set of situations, mostly involving heinous crimes.
Citizen! You have attempted to influence the thoughts or actions of another! Hold position and await the arrival of constables who will arrest you for violating the Anti-Groupthink Act 2016!
Your thoughts jump to police and coercion all the time. Why is that? Nobody is trying to coerce you to anything, unless you see other individuals voluntarily associating as some kind of coercion on you.
People discussing with whom they will or will not associate is, in this very HN thread, referred to as "tyranny", "despotism", "blackmail", "extortion", and of course you yourself went for the oppression/"thoughtcrime" angle.
Yet one satirical comment lampooning it is "jump to police and coercion all the time" and "why is that".
I suggest you get checked out, you've got more projection going on than an overbooked IMAX theater.
