How is Russia the 'bad' guy?

Why is the world up in arms because Russia is defending an ethnic population from the Georgian Government? I’m looking at all the information about this and I can;t see for a second why the media and people in general are supporting Georgia on this one? (especially considering that they support the formation of countries like East Timor, Kosovo etc. and the South Ossetian invasion by Georgia is a direct assault on what has been a de facto country for many years )
