Wakanda: Why the controversy?

So, it appears to me that whenever the issue of how Wakanda should be presented in live action comes up that the debate gets acrimonious very fast. There seems to be something about the subject that brings out strong feelings. Whether it's wanting to tamp down the level of technological prowess of the Wakandan nation or the problems posters have with the idea of a scientifically advanced yet isolated society. Yet there is no one claiming that Asgard needs to be less exotic and in need of suspension of disbelief but Wakanda being a closed but advanced nation seems to be a bridge too far for some, or at least it provokes some very heated exchanges here on the Hype. Why?
