It's textbook overcompensation.
Without going much into details, both Russia and the US are far from being angels (Russia moreso than the US), but mainstream western media does make a serious effort at times of putting the US, or the West into the best possible light, while Russia is demonized (case in point of course the Ukraine-crisis). As a result, some of the people who notice the discrepancy of the media's coverage, turn to the other extreme and completely overlook the massive flaws of Russia's policies/actions.
