Fifth principle: The right of conscience and the use of the democratic process within our congregations and in society at large.

This is one that I think doesn't really have a connection to druidry. It's not that druids are against using the democratic process; it is just something that does not come up. Many are single practitioners, so a democratic process isn't likely to be of much help with one voter. In a grove, I can see it being a good way to govern, though not always the best way to write a ritual. setting goals and deciding where to spend effort and money are more likely to be amenable to a vote. Allowing everyone to have a say increases ownership in the group and can, if done right, increase the cohesion.
