A Centrist is someone whose political ideals
fall between liberal and conservative.
The Centrist does not try to walk that non-existent middle ground but rather rejects all extreme partisan positions and chooses instead to look at things from a different perspective.
Some people try to sit on the fence and make a stack of partisan issues, picking some from the left and some from the right. That's not centrism, that's insanity. It's like driving down the middle of the road and trying to dodge traffic coming at you from both directions.
Some people suggest there is always a middle ground, and people with opposite opinions can just come to the table and work out a compromise. That too, is insanity. It would be like expecting "Black Lives Matter" and the "Ku Klux Klan" to agree on a compromise solution.
The Centrist rejects partisan positions and looks for non-partisan alternatives. It seems obvious that when we are pressured to side with one or the other of two diametrically opposed "cures," we are being fooled into worrying about symptoms instead of treating an illness.
The gun "issue" is a classic example. It is framed as either "there can be no restrictions on guns" or "take away all your guns." The polarization of the issue overshadows the problem of living in a country with the highest rate of mass-shootings and the largest rate of gun violence in the modern world. The problem will continue to grow and fester until we step back from the partisan grandstanding and look rationally at the problem.
The Centrist takes an analytical approach to recognized problems. He starts by correctly and clearly stating the problem, then uses an expert-driven, consensus-building approach to finding a solution.
