One of the major topics I write about is institutions and the flaws built in. Institutions, out of necessity become self-serving. Also there's the asshole quotient- no matter how noble the original intentions of any institution, movement, organization, etc,. it will inevitably be usurped by its worst element.
The worst thing that happened to the Church was the Council of Nicea (325)- it became an institution and it's been downhill since!
