Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
Darkrai is the Porygon of Competitive Pokemon. Unfairly persecuted by the actions of a completely separate mon (Smeargle/Pikachu), and forced to forever suffer because of it.
I genuinely imagine GF is just unaware that Defog is even something noteworthy to begin with. Hazards are barely used in VGC, so to them Defog is just a random evasion debuff move that was a HM in Gen 4.
Clearly in the rumored Unova game we're going to unlock Meloetta's true form by playing the entire playlist of the Vocaloid collab why doing a highly choregraphed dance on Mt Kilimanjaro.
The manji is not the swastika. To suggest such is genuinely offensive.
Also, Jynx is most likely intended as a fairly grotesque caricature of gyaru culture grossed with a yuki-onna. That accounts for the blond hair and black skin. So yes, it was intended to mock.
You forget that the game itself explicitly points out that the time machine is not the whole story, since as Arven points out Heath witnessed the Paradoxes centuries before his father/mother performed their experiments.
