The foundation of a society is its families. The foundations of a family is its marriage. Marriage needs to be reinforced, not redefined.
Advocates of changing the definition of marriage love to tell me to mind my own business: that what happens in their bedrooms doesn’t affect me. Well that may be true, but I didn’t try to change the laws, the constitution, or the institution of marriage itself. What you try to do in my country’s government absolutely is my business, and you can absolutely bet I will not be silent when you take your business from the bedroom to capital. You made it open for public debate, so don’t resent a public debater.
