No Bob, there is not an issue.
You, and others making arguements like this, tend to overlook the poses struck by male characters for the most part as being equally revealing in their own way. The overwhelming majority of those characters are showing off features like their oversized arms, or smooth, pretty boy looks in the course of striking those poses. If you didn't know anything about the characters in question, they would just be generic musclemen, male models, or chippendales, the same way how Mai would just be a pretty girl.
When commenting on the greater diversity among male characters, that's not really an issue either. Both genders represent something of a physical ideal in video games, granted it might be a fringe ideal, but it's still there. To use E-Honda for example, there are people who work their entire lives trying to get a perfect build for Sumo like he has.
When it comes to support characters just like your portly merchants and such, you have the matronly barmaids and old crones and such filling out the nooks and crannies of villages. Not all of the spectators in the backround of say a fighting game are universally good looking for example.
Now, I will also say that there is also a bit less practical diversity in women for the kinds of games presented, because there is some relevency to this in real life. If you look at female dancers and martial artists and such you'll notice they all tend to wind up with the same, or very similar builds. In comparison guys, who are designed differantly for physical activity, can be greatly more varied in the way they develop. There are books on bodybuilding and body sculpting that are dedicated to this kind of thing. Saying that say Mai and Chun-Li have more physical similarities than say Ryu and Sagat is simply the kind of results your going to see from the training given the building blocks. To use perhaps a better example comparing say a Zangief to say Tina (Dead Or Alive), or say again Mai, you could say "well why isn't Tina bulked up like that, and is instead still built more along the martial artist lines", look at the real world pro-wrestlers those characters are based off of. A girl who does all the same moves that the guys do, and trains the same way, still winds up developing along those same basic lines, where a guy can show more signifigant differances in overall body bulk and mass.
In most cases game developers are looking at the sources that inspire the fantasy, and producing idealized versions of it. Do Zangief seem like idealized fantasy versions of live performers like the old Nickolai Voldkoff or Sable (back before she got kicked from wrestling)? Yes... they cover that well.
The reason why feminists are treated like they are making an issue out of nothing, is because they are. Their basic arguement is that we shouldn't have idealized depictions in video games or fantasy... or at least not of women. Generally because they feel men can't handle it or whatever (but of course their Chippendales stuff is fine ironically).
There is no pretension that the audience is a bunch of teenagers, heck the gaming media has been talking about the average age of gamers rising for a long time now, and the female characters we're talking about are frequently from "M" rated games (because of the sexual aspects that might be present). Teenagers couldn't have kept this arguement going on as long as it's been going on through the gaming community, they would have been stomped by the feminists long ago. The battle isn't being fought with kids, but between adults.
I don't see this as a case of being concerned about feminists "ruining our fun" so much as the whole arguement as being stupid. Especially seeing as when women produce idealized, fantasy artwork, it comes out exactly the same way.... which is a point that is almost universally sidestepped in these discussions.
