I'll agree with the fear of the unknown...Alot of people that tend to be anti-gay change their tune when a member of their own family turns out to be "one of them". They can sometimes then become some of the most ardent pro gay supporters. I think it has to do with issues not really touching them....
The govt thinks they can regulate every aspect of people's lives & that just rubs me the wrong way. I've NEVER understood how two men or two women being "married" suddenly makes the union of John & Mary endangered. What does what I do in my own home have to do with what you do in yours?
