I will respect this opinion if, and only if, you can come up with a legitimate reason why. All the arguments I've heard against gay marriage are Bible-centric and the people who make these arguments coincidentally have never heard of Deuteronomy 21:18-21
This is how they served justice in the 4th century. Eventually a law system was put in place when people got together and said, "hey, maybe we shouldn't immediately stone him. Perhaps we should allow the person to make their case." You know something like that. Anyhow, that some old school justice right there.
