The mindset that confuses me about "we need to be more progressive in comics/games/etc" is that it's essentially targeting an audience that was never a large demographic for those things previously. Not to say you can't add those things from time to time, but the approach of forcing everything to be entirely different from what fans generally enjoy is confusing to me because you are alienating your core audience in hopes of trading it for an audience that historically doesn't buy your product, so the idea of "progressive" content being shoved in is essentially falling on deaf ears minus an article or two. It feels like it's there more to allow creators/writers to pay themselves on the back and feel special as opposed to doing anything genuinely interesting or different.
So for example, Lee and Romita having Harry be a drug addict went against the Comics Code, which was extremely bold and (though unintentionally) a strong win for making mainstream comics a more mature medium that allowed more story ideas to develop. It didn't alienate anyone because the content was still the same, just with some changes that didn't infringe on the quality of the comic. But, say, replacing male heroes with female versions or white versions with black versions is forcing out characters that are established and loved and doesn't do anything positive for the comic, especially when all you do is bring up how progressive they are (i.e. The infamous Whor/Titania pages).
