I agree with her completely. I don't like the term "married" for two people of the same gender. That is not knocking their relationship. I just firmly believe that the term married means a man and a woman. I got flak for my beliefs on canada.com but regardless - I still feel the same way and I'm sure there is nothing that will change my mind on that.
And some believe it means a man and his harem (which is the historically correct definition),
I only see a problem if someone forces you to change your relationship. I have no problem with how you define marriage, unless you try and force your definition on me.
Its supposed to be a free country, and what that really boils down to is people are free to do things that bother the hell out of you in their personal lives.
