1) Countries are really big. There are multiple layers of sub-community, providing for much more diversity even in a country that isn't about diversity. LW is multiple orders of magnitude smaller than Britain even with lurkers counted, and if we only count the regulars, the same can be said of magical Britain.
2) Countries don't have a specific purpose. Websites often do (including this one, used in the example). On a website, simply going off-topic badly can be a bannable offense (not here, yes). A country trying to do that is farcical.
3) The example given above, that I was responding to, was about someone who was let in to LW, did some bad things, and was banned. This is the equivalent of exile. It was targeted and in response to an existing wrong. It was not done proactively for a broad category of people who had not done anything wrong.
4) Speaking of those people not doing anything wrong, "don't, won't, or can't accept [the community's norms]" might be a legitimate reason, but it was not the criterion applied in the example, even approximately.

Yes, but you still need standards for said sub-communities to be able to coexist.

Depends on the website and the situation. Hacker News, for example, temporarily disables creating new accounts whenever it is linked to by a mainstream source. Also if a bunch of people from 4chan decided to show up here, I suspect ...
New chapter!
This is a new thread to discuss Eliezer Yudkowsky’s Harry Potter and the Methods of Rationality and anything related to it. This thread is intended for discussing chapter 102.
There is a site dedicated to the story at hpmor.com, which is now the place to go to find the authors notes and all sorts of other goodies. AdeleneDawner has kept an archive of Author’s Notes. (This goes up to the notes for chapter 76, and is now not updating. The authors notes from chapter 77 onwards are on hpmor.com.)
Spoiler Warning: this thread is full of spoilers. With few exceptions, spoilers for MOR and canon are fair game to post, without warning or rot13. More specifically:
