I don’t think it helps to talk about a one dimensional political spectrum. Left to center to right. Attempting to shovel all political issues from dealing with the homeless crisis to tackling climate change and foreign interventionism into one of three boxes, left center right is infantile and creates partisan behavior.
You are right, political issues are three dimensional and can best be pictured as spheres overlapping each other sometimes and other times floating alone. Where we sit as individuals on those issues can’t be labeled as left or right. We should drop our partisan loyalties and start talking about issues to find common ground.
