it is in no way shape or form any of your business what another human being decides to do provided it does not cause physical harm or in some way is cruel. Gay marriage is a right just like normal marriage is. If someone wants some mumbo jumbo magic ceremony and the blessing of some magic dude in the sky then really who's business is it to stop that.
If your against gay marriage your ignorant, plain and simple, and I will never look at you in any other way then that. This issue goes far beyond the issue of god for me personally as it is something that actually happens in this world that is tangible, therefor it has an actual anchor for me to feel an emotion towards it.
