I'd like to make a general point about this whole debacle, which is confusion over matters of scale.
1) It is not
wrong for any one person to want to make a sexualized female character, as long as they are aware of what they're doing and the alternatives that exist.
2) The problem arises, however, when
everyone is doing the same thing, to the detriment of both the creators and the audience. It's a feedback loop, where the objectification creates a norm that is adopted by the audience. The norm shows up on market research, which influences more creators to use the same methods of objectification. Alternatively, you can think of it like this. These same creators themselves were once audience and are now perpetuating the same norm that existed when they were in a consumer's role. See: Comics -> Browder
3) Change, no matter how wide scale, has to start with the individual. You might think it's unfair that RPS "ambushed" Browder, but who is a good target to "ambush"? Is anyone? Should we just not confront this issue at all and let time solve it? No, I don't think so. Eventually, someone has to take the initiative if change is going to come in a timely manner. And, to be honest, I think Browder is a much better target than most other developers, because of his veterancy and pull within Blizzard, which produces so much of the gaming content that falls into the categories of "objectifying" or "sexist". It's sad to see how uncomfortable he was with this line of questioning, however, and I'll doubt he'll change his mind about it in the long run.
One of the hardest activities for most of humanity is to articulate themselves well when being ambushed with loaded questions from a interviewer with a clear agenda. Your supposition could very well be correct, but it can equally likely that the interviewee is not skilled in such situations. Considering he is a game developer and not part of the PR, being flabbergasted isn't really indicative of guilt as you see it.
I'm not really trying to villify Browder although I can see how I might've come off that way. I was thinking more about how Browder is potentially representative of a lot of senior game developers (and a lot of gamers at that), people who are ultimately products of their environment and are not so much "bad" as they are unaware of the potential damage being caused by what they think is just harmless fun. HIs comments about how "We're not running for President" is especially telling, because it seems to me that he is in denial or disbelief that he has any sort of responsibility or culpability regarding this problem, and that he's just a lowly game developer (whose vision just happens to reach millions of people worldwide) and what can he do? This "it's not that big a deal, is it?" mindset is probably one of the biggest obstacles this industry needs to overcome if we're going to get anywhere on this gender thng.
