Female readers care. All fifty of them. The comic industry knows who their target market is and caters to them. If you don't like it, don't read it. This is a free market in a country that has free speech. If the comic industry thought it was a good idea to change their formula, they would. They aren't purposely giving up market share so they can continue to exploit women and minorities for fun. The comic market is incredibly small and changing the formula may not have good results, even if you, the female reader, feel better about yourself.
You ought to be aware that free speech allows for these things to continue and the free market satiates the demand. Eliminate our rights and control the market and you can have your perfect little world.
If you want to get their attention, you need to stop giving them money. By purchasing their products, you are saying it is ok to continue doing what they're doing. You can yell and scream all you want but in the end, if they have your money, then you must have liked their product and they will continue to make more.
Marvel realizes what they're doing with their characters because they change them for the screen to make them less sexual or whatever and more desirable to the masses. The problem for the comic book as a form of media is that it has a narrow appeal. Those that purchase comics have been speaking for a long time and this current form of comic book is what they were demanding.
Note: I agree with your general desires for the industry to change but I am under no illusion it will. I don't purchase comics and therefore have no say in the market. I really do agree with you.
A cynical view, but I hear what you're saying. And I'm not saying it should be illegal or that we should take away anyone's rights. I'm suggesting exactly what you are - for comics readers, don't buy those comics, send a message. Apathy or indifference just doesn't help.
I do disagree that it won't change, though. It IS changing, imo. Have you taken a look at Ms. Marvel recently? She's Captain Marvel now for one, she's not overtly sexualized in her current series in the slightest, and it's a wonderful book. Sure, it's just one example, but it's also one step in the right direction of a very uphill battle. The change will come faster when we start supporting books like that, and stop supporting the trashier, exploitative ones.
I have no rebuttal, it was a *****ey thing to say there's no denying that. and I'm very sorry if what I said made you or others angry (which it clearly did), I just don't think people should be shaping their opinions through what Ms Marvel looks like on the pages of a comic or what Beyonce looks like in a commercial.
I know that the sad truth is most people are affected by those things, but it's silly to me. If I feel self conscious about see Ryan Reynolds six pack and not having one myself then I'm going to get off my ass and go to the gym not loathe in self pity when I see him on TV.
I don't think its as much a fault of the media using sexual appeal to sell a product, that makes sense. But when people see those outlets and then flip it into themselves not being up to a certain standard that's all a personal problem not the media.
But I really don't want to argue personal feelings on equality, I think we share a similar feeling I just get frustrated when people let the media mold their minds into what one should be and I took it out in a childish way with my comment.
No worries, we all make thoughtless comments every now and then.

I do think we're on the same page, but I should add that whether or not we
should allow the media to shape our perceptions, the fact is that most people do. And considering that that is the sole purpose of the media's existence, they can't plead ignorance or claim zero accountability for that. It's why they offer apologies or get fined by the FCC all the time - because we all know that what they choose to show actually affects people. And they do widely perpetuate the casual systematic misogyny, xenophobia, homophobia and racism that permeates our culture through their choices of portrayals. So I do think a lot of the responsibility does fall on them, but yes, it is also up to us to form our own thoughts and opinions based on what we see around us and the information we have. The thing is though, the majority of what we see around us and most of the places we get that information from is through the media in some way, so it's something of a vicious cycle.
