I think people just don't like the genders being treated differently. If manshep had been very petite and slim, no one would be complaining about femshep being petite and slim. People who appear skinny can of course be physically capable and strong but it's not visually apparent (and you want visually apparent in a video game) and the skinny people most of us know in our daily lives are those without any muscle tone rather than those with lean, strong muscle so a lot of us have that visual association. Add that to the fact that skinny women (and skinny women with large breasts) are the only kind of woman you usually see in video games and it becomes very disappointing to have femshep fit that as well. You finally get a legitimate female hero and she's a soldier, a role that makes sense for her to be beefier and more defined (unlike characters such as princess Peach) and she still has to be thin and petite (and they even held a beauty contest for her before ME3). Sorry muscular ladies, it's still 20 years too early for you to think about being represented in a video game.
Yes, I know all of this. I was only pointing out that it was nonsense to say femshep wouldn't be able to do her duty because she is skinny. Wanting a muscular female is perfectly fine, but it's a visual and role playing preference. It's quite different to say, "I'd love to have a muscular female because it fits in with what I imagine a soldier/warrior to be. It helps my immersion." rather than, "Having a skinny female soldier/warrior is stupid. No way someone so skinny can be one of those."
Not only is that untrue, it's a form of body shaming. That is the only thing I was pointing out. I wasn't touching male/female equality, etc.
In closing, femshep may have been skinny, but she didn't have large breasts. They were very proportioned to her body type. I get what you mean about it, though. And to be fair to Bioware, I don't think they meant for it to come off as a beauty contest. People wanted a femshep to be represented and
I think it was more about getting the community involved into the planning and design of her. Unfortunately, it turned into a hot mess. I think they had the best intentions, but I am sure you know the old saying about that.
