It will to some degree.
" hey there are less harmful stereotypes and tropes in our games and more other things "
And you should want that, as a human being I assume gives a shit about other human beings. Who's gaming experience , i assume, does not completely rely on those things being in your game.
They aren't all gone just a bit less that and more new stuff. Life is change, sometimes less of thing happens.
1) every Creator that isn't like Godamned Kojima and even then, gets things forced into their game. EVERY SINGLE ONE OF THEM. Because its a crew making the game, their vision almost never comes out raw. Please end this fantasy that game design is directly like an artist with a paint brush. It isn't it takes a long as time, and teams of people who a lot of time get say into what works and what doesn't. Along with the notion that investors also have some say that goes in, and can be the ones inserting these harmful things, so the 100% un censored version of the game so desire might not even have those things in it. How games are actually designed most times, completely defeats your logic entirely.
2) Besides culture as a whole gently "forcing" people to lessen the stereotypes and greaten the inclusion. Besides aforementioned forces no one is forcing anyone to do anything, suggestions. No one is being hostile, all we are are suggesting things.
Now you've clearly stated you do want to stop the production of certain things. You think the weight of morality is on your side in this. That's an argument worth having. Perhaps you are right, but it also becomes clear why people might disagree with you. They think the weight of morality isn't on your side and you're doing harm by stopping the production of those things, or perhaps they agree with the moral force of your argument but view stopping the production of those things as a potential greater immorality (e.g me),.
"We don't want to take things away and anyone who says we do is just crying censorship even though at this exact moment I want X to stop being portrayed" isn't an argument worth having, because no possible argument can exist against "We aren't doing anything so I don't see why you're getting upset".
I don't care if a lesser percentage of games are of the type I like (frankly as someone who's primarily a turn-based JRPG / SRPG fan, I'm used to it), but I do get concerned about a reduction in the absolute number of things because that tends to lead to a spiral of disinterest which ends in very small numbers because everything is profitability/focused tested to death.
If you want more games with greater diversity and you achieve that through producing more games then I not only have no issue, you have my active support.
This is probably where our disagreement occurs, I want more games that (insert group here) are comfortable playing but the idea that the only way that can happen is if you force things like Dragon's Crown to not exist is one that strikes me as deeply wrong and something worth fighting against. Just because you've been oppressed doesn't give you the right to oppress others.
And even some of the stuff that features stuff you dislike you may quiet enjoy e.g I'm an agnostic (in the sense that I acknowledge that we cannot be certain that divine beings/forces don't exist but I'm reasonably certain that if gods exist they certainly aren't those of any existing religion as written) but I still have a pretty high opinion the Chronicles of Narnia, despite them being thinly veiled Christian allegory.
