Why isn't the language of this post set to "German"?
Because it's targeted at users who don't necessarily include german in their language settings.
If they don't want to see German content and you make it so that they do see German content, that's a bit rude, isn't it? If you don't want to see content from a specific user and they just create accounts to make you see their content, you'd be a little bit ticked off too, wouldn't you?
