I don't often call myself a liberal these days; it seems I get more conservative as time goes on. But my conservatism is born out of my earlier days as a liberal.
It is out of PTSD from being bullied as a child, that I recognize the bullying inherent in the pro-choice choice of who will live and who will die.
It is out of respect for nature and sustainability that I'm a conservation style environmentalist- and a sane one who recognizes the human need for agriculture and the role agriculture plays in preserving species.
I am not comfortable with libertines or libertarians. But my conservatism comes from an understanding of systems, and how systems work.
