Well there's a line.

If that sub has just become a cesspool of racism and toxicity to the extent where it has completely prevented any actual discussion that deviates from the typical "BLM are the real racists, refugees should drown, femininazis are evil" then I'd say the moderators should take actions. Whatever they choose for that. If they want to make a toxic echo chamber fine. But it shouldn't be called /r/european. I loathe KIA, but I don't object to it, just steer right clear.

It's no longer fulfilling it's purpose as a debate sub and ostracising a wide range of potential contributors. I also think the mods of /r/politics are absurd. No idea why there are two Bernie echo chambers.
