Not a whit, because after considering the situation I have concluded that same-sex marriage, while it may offend them, does not harm them. There's a world of difference between offended and harmed. My thought process goes, "hey, I can see people being harmed by not being able to get married to the person they love, while these people over there who are offended are going to be just fine not-gay-marrying each other."

I think those who prioritize their offense over others' harm really do lack empathy. (This is why, despite a personal dislike of a number of rather loud social justice activists, I'll go to bat for the causes that they support, while I can be offended by their conduct, they are right and others are being harmed. I am an adult and can put up with being offended to help others not be harmed.)
