Anyone finding what @rok-sivante is writing as a bit on the controversial side might find that much of what is taught in popular media in western society is enough to divide otherwise good people by nothing more than social constructions that result in the evitable anger - otherwise understood as cognitive dissonance. Bliss (1997) and the superb performace by Terence Stamp as the teacher for those who've had no success from the best marriage counselors, brought this tricky to understand concept to the mainstream (although so few ever saw it) with superb tact.
