Gaming is fun, and fun is for everyone
Honestly for now I just ignore Chris Perkins post as nonsensical and I encourage others to do the same until what they are up to becomes clear or they change their minds again.
More seriously, just because a character has visited another world, does not mean they are suddenly "that setting's character." Mordenkainen also has his own tower on Avernus, but I wouldn't say he's a Nine Hells or Planescape character.
If I asked Gary Gygax if they character he made was a "Forgotten Realms character," he'd probably laugh. And then ask me to leave his cemetery.
