Some of the most disturbing and tense atmospheres I've experienced is when people worked up about their politics (usually by others) are fearful their their sued is about to lose or has already lost an election. It's the closest thing I think I've seen to mental illness without the people involved actually being mentally ill. Over the top outrage over the supposed positions of the opposition ofter when their political camp did similar things first and they had little to no outrage. Paranoid about an impending doom. Accusations that the opposition is evil. Accusations that those who support the opposition WANT to see the destruction of society. Knowingly making false assertions of supposed moral character deficits of those who support the opposition. Vilification of anyone they do not personally view as wholeheartedly supporting their side including people still deciding which candidate to support. The use of violent metaphors in describing political discourse. In some countries real violence is sadly seen.
I remember a while back having lunch with a group of friends around election time. One of the people in our group casually mentioned he wasn't sure how he was going to vote but didn't buy all the negative hype surrounding one of the candidate. Another guy in the group practically lost his mind and I was afraid he was going to start throwing plates at the restaurant.
Sorry, poll didn't post. Not sure what I did wrong.
