Here is a google image search of various political spectrums.
The main thing they have in common is affinity for bullcrap. They distort and oversimplify. They use euphemisms for establishment totalitarianisms. They use dysphemisms for outsider beliefs. They omit beliefs based on accurate reasoning, limiting the range of thought. Some spectrums emphasize psychological categories rather than policy beliefs. They assist establishments in getting individuals in to join establishment teams rather than getting individuals to weigh the evidence on specific issues, leading individuals to think the are morally superior based on team faith, as if politics should be a ruthless sports contest.
To hell with them all.
