Because politics has finally hit the point where it's more about saying "FUCK YOU" to the other side rather than actual policy. Misleading news, fake political posts swarming social media etc. People are uninformed and emotional versus educated and responsible. Who would have thought all of this information and knowledge at our fingertips would just be wasted.
Personally, I like to think we're getting better, it's just the fringe sides getting the headlines because that's what makes for good stories.
