Why do people insist on turning every news article into a political fight?

Regardless of what many people reading the Question title might think—this is not related the attacks on US Embassies. This story describes a situation which occurred in Sweden where an intoxicated man falls off a train platform, but luckily there was a bystander who saw him fall.

Unfortunately, the bystander did not go down onto the tracks to save this man’s life, but rather to rob him of his valuables. Once the robber took what he wanted, he jumped back onto the platform and walked off. The guy who fell eventually got hit by a train, but luckily he did not die, but is rather in critical condition and had part of his foot amputated.

I went down to the comments section of the story, and these commentators (trolls) turned this story into a political debate! Are we as a society so polarized and politically-crazy anymore that we cannot take a story which has almost nothing to do about politics and then use it as ammunition to fuel a political debate? Am I just going crazy, or has this time in our lives escalated to a political hate climate of no return?
