(going to continue the above structured 4 bullet points)
1) Stories are today more homogeneous then ever before. People used to joke that you could set your clock to a james bond movies, and know what plot, what characters and what events will unfold. Then other movies copied it, and they too could be set to that same clock. Asking for originality is what we consumers should do but it is not what sends money to the bank if you are a producer. I would not know how we even could began fixing this.
2) video games do not present a wide variety of male types. Since when did you see a undecisive, meek, emotional erratic male protagonist? How often is he a gear of wars massive hulk made of 99% muscles, with so low base sounding voice that he likely has a serious sickness in the throat? How often doesnt he act like an emotionalless robot, creating a flood of corpses and steals anything that's not nailed down?
3) while I am not a game developer, I doubt that having strong women would lower the numbers of sales to boys. I don't see anyone arguing this. I do however think that the industry is lazy, and is not going to change their products if they don't have to. Movie producers and game producers are in this aspect very similar, and focus on what ever sold the most yesterday. In media, only books tend to have reached a level of diversity that we as a society is happy with.
4) I don't think the commenter is angry. That would imply intent in a very few written lines. I also think you are missing the point. Stories are complicated, and good stories require more than simple resprite work or pronounce changes. This goes same for making games that present role models for boys as well as girls.
