Totally get what you’re saying. Analyzing your media is good. Even finding or making an arguement for darker themes or making up a “darker” version of non dark media is fine, even sometimes great or funny in a good and intentional way.
And i don’t have a problem with someone doing a dark analysis of pokemon, whether i agree with it or not. What i think deserves derision is how it comes off as “unlike you, I a smart and serious person was always aware of intended darkness and adult themes within this massive commercial children’s media. You may not like it, but this is what peak analysis of Pokémon is.”
