These kinds of acrimonious, partisan political discussions only occur in places where democracy has damaged foundations. In America, this is caused by the "winner takes all" style of state-level national vote, leading to gerrymandering, battleground states, strategic legislation, and a two-party system where most people don't feel heard or understood by either party, and no politicians other than the idealists will run independent or with a 3rd party. When things feel broken enough to be threatening, politics get nasty, and the rest of the world watches on with worry.
