To be blunt she is just ignorant to the subject matter. A lot of people judge video games based solely on pre conceived misconceptions. Unless she wants to become more educated on the matter and actually learn about the medium you can sit there and argue with her until you run out of oxygen, she isnt going to listen. This applies to pretty much anybody and gaming. I just had a recent issue with someone calling me a "child" because all video games are "made for children". It didn't matter what I said he wasn't going to change his stance on this.
As far as this and being married now man thats a tricky one. I say stand your ground unless it really really creates a problem. If you dont judge her hobbies and interests than she should treat you the same.
