(from the article Where's the harm in gay marriage? by Andrew Coyne in the National Post)

The vast, vast majority of marriages will continue to be between a man and a woman. It is difficult to see how the commitments they make to one another on their wedding day could be one bit weakened merely because, somewhere in Canada, a homosexual couple was repeating the same vows.

But then, as we are often reminded, this is about so much more than whether homosexuals should be allowed to wed. The issue has embroiled a number of society's basic institutions: family, Church, Parliament, the courts. It engages some of our most deeply felt needs and profound beliefs: sexuality and spirituality, minority rights and majority rule. No wonder it's such a big deal.
