You can't label queerness as a purely sexual thing because it makes it sound like you believe all queer people are all like sycophantic perverts. Also mind you queerness also deals with gender identity which is not sexuality based at all. From the logic your pulling, games with trans character on this site should get pulled because its based on "sexual stuff". The fact people generalize queerness as sexual stuff is actually one of the main reasons creators who are making queer experience games are also worried.
And just a larger addendum but for gods sake if you hate nsfw games this much not only are they're deindexed right now but you can also filter them out with tags and settings. What are you gaining by trying to stoke fights with people in the community forums? Are you trying to get itch to make the change permanent instead of a temporary measure? The itch staff barely even read these forums and also disagree with you. Just go enjoy all the games on the site you want and leave these people alone because all you're doing is making yourself look like a moron with the times you've put your own foot in your mouth
