In general it can be seen to be rude to say go into an ntr game thread and post about how much you hate ntr games or whatever genre you don't like or wish the game isn't what it is.
I don't have much issue with your post, but understand that the cumulative effects of said style of post can be the straw that breaks the camel's back for some people, whether that is reasonable or not.
It's totally fine to have wishes or opinions just don't be surprised if others take issue with it.
