I like to think of myself as an activist--someone who stands up for what I believe is morally sound, regardless of opposition. However, I had to pray for desire to join the movement for Proposition 8. I have friends and acquaintances who either term themselves "gay" or say they have "same gender attraction." I love these friends, and want their happiness. A portion of my morals says, "Let them use their agency, and learn from the consequences--just stay out of all this fervor."
But as I prayed for how to reconcile these feelings with the clarion call of my church leaders to defend Proposition 8, I felt an empowering realization: Aside from having a moral obligation to allow for agency of others, another part of my personal moral belief calls for protection of the sacred.
Sacred means, in one dictionary definition, something holy that must be "secured against violation, infringement, etc., as by reverence or sense of right." Marriage, as an institution given by God, holds the title "sacred" in my mind. If marriage becomes allowed to describe unions not sanctioned by God (i.e. same gender unions), the term will have been "violated." Therefore, I feel a motivation to secure this institution against infringment, and urge others to do the same.
