Contrarian, no, not really.  I believe in the golden rule (do unto others...) and speak out when I see the concept trashed.  Regarding juveniles, it seems your position that adulthood should be set to 15 years which is when driving permits are available.  That is a societal decision.  I wonder if you would be self-consistent and say that 15 year olds have all the rights of adults since they would have all the responsibility.  This would mean that they should buy booze and cigarettes.  They should also be able to consent to sexual relationships, etc.  Or would you assign responsibility but withhold privilege?
