Just because someone enjoys the romance part and is vocal about it, doesn't mean they're automatically diminishing the game in any way and want to make it worse or overlook other issues. Some might, true, but I see a lot of generalisations here.
It's about the romance stuff diminishing the RPG genre. The romance content gets larger and more involved while the core elements of RPGs, e.g. the combat gets dumbed-down. Look at character creation players used to agonise for days over stat allocation now it's agonising for days about hair styles and tats.
After all BG3 has shown that you do not need a good story, balance, fluid mechanics, a working 3rd act or endings to sell copies and get showered with awards as long as you can satisfy the thirsters with nudity, kisses, waifus and cringeworthy sex scenes.
And let's not forget about the hype, the hype and the more hype or the lies, bullshit and promises about what you the lucky gamer will get 'tomorrow'. Meanwhile Hotfix #15 just dropped. Is that the third or fourth since Patch 5?
