I think my most controversial idea underlies many of my controversial opinions. It's that I don't believe that personal decisions have no impact on the rest of society. I'm always slightly bemused when I hear people who are past their teens arguing that "if it doesn't bother you, if it's my life, why do you care?" It seems like a very self-centred view that doesn't consider the impact of one's decisions on one's neighbors, one's society and culture at large. I think we have to consider how individual decisions and what we deem acceptable transform our cultural values and standards.
