As a pastor who does believe marriage is between a man and a woman, I don't have a huge problem with this.
We have some "Christian" churches that deal with this topic in a very hateful manner. We have seen them on the news and there have been documentaries created about them. These people that call themselves Christian are filled with so much hate that as a pastor I have to think that there is very little room for God in their hearts. They give all other Christians a bad name because they have the bigger mouths and we as Christians tend to stay silent, which helps the media and others, combine us all into one group. Shame on us.
