'wat if humanz r the real monsterz
' is one of the tropes I utterly despise.
The Witcher 3 wasn't a perfect game but it did an excellent job with some of its quests. The Bloody Baron, for example, is a reprehensible individual at a glance but as part of the quests exploring his backstory you quickly learn that things were not as black or white as they appeared. I have little doubt that such characters will be sorely lacking in the upcoming sequel.
That being said, I think it is also worth pointing out that content creators are often given marching orders from their paymasters, agents and contacts in the industry. There's a high chance they're pushing the idea that anyone with concerns relating to the story and canon consistency is just a 'tourist' as a desperate attempt to deflect and silence criticism.
