I have no problem with anyone opposing gay marriage. Every individual has a right to believe what they believe in. That is the very definition of freedom of religion.
What I do have a problem with is the arguments presented. “We must preserve the sanctity of marriage.” “We must protect the children.” Half of heterosexual marriages in the US end in divorce and 63% of all children in the same country grow up away from their biological parents. If these groups cared about the sanctity of marriage and well-being of children they would have focused on that a long time ago. How do we prevent divorce? How do we prevented undesired pregnancies?
Please don’t try to pretend that this is not based on your personal faith and the doctrine of your religion. I would respect you a lot more if you would just be honest about why you are against the rights of gay citizens. To pretend that you are doing this for “the children” or for an institution that has been failing in the US for the past 20 years makes no intellectual sense. And you’re not stupid, are you?
