To me it looked like you were just saying. "Look at this. *describes it* This is interesting. Discuss."
The line you quote seemed to me as "This is a good way to get started to get into the discussion."
Oh come on, don't say that guy is an idiot. He was trying to help her and spoke well. Even if you think he's wrong, that doesn't make him an idiot.
Me, I think this is a "problem" that will solve itself in time now that the female gamer base is growing and gaming stories are forever getting more complex. The damsel in distress mechanic is already fading away, though there is now a rash of scantily clad pretty girls in gaming that I think is the bigger problem, but again, I think this will eventually wear off now that graphical capability is not advancing so fast. I like complex and strong female characters. There's nothing wrong with pretty girls, but there is when they swamp the character types like they do. I would much rather have a female character in an RPG clad in armour who looks like she could kick your ass than a girl in what amounts to a bikini. However, I'd have no problem with both in the same game, then you'd have variety. Keep your pretty girls, but give me something different, give me a girl who's like mid 30s, with scars and some heavy muscle, that would be something different. A lack of muscle is something that annoys me, all these skinny girls, why not have a scantily clad girl with some muscle on her body, then I can take her seriously when she's wading through the bad guys. I think developers are lazy with female characters. They often feel like Generic Pretty Girl #1524.
There is one game which springs to mind though, Code of Princess, which I watched someone Let's play. This game features the titular character as the main protagonist, and she has the skimpiest outfit I think I've ever seen on a female video game character short of something like bikini beach volleyball or the like. And yet I came to like her character and the direction the game went in general when I watched the LP.
