Yes, it really is that bad. Think the US is immune? Think again. (Some strong language).
It is always risky to attempt to explain metaphors—especially someone else’s, as the title comes from the guy in the video—but due to popular demand, here goes: Tumblr is a powerfully equipped micro-blogging site, that seems to be the fulfillment of Karl Kraus‘ comment, “A journalist is a person without any ideas but with an ability to express them.”
Graphics and other forms of media are heavily featured, as is pornography. I think the idea is that Sweden is now letting any lunatic have total freedom to pollute the common environment, as if this were a virtue. Since rape (if perpetrated by immigrants) is all but completely tolerated, the porno of Tumblr comes to violent life in Sweden.
