You are contradicting yourself again. You want any action not possible by the understanding of Earth physics to be called out as supernatural or magical UNLESS the fact of that action is blatantly obvious... well... a man punching through a steel wall because he is inhumanly strong is blatantly obvious, just like dragon flight, so it doesn't need to be called out, right?
The problem is, you think dragon flight is blatantly obvious, but actually to most people... it isn't. Most people are not familiar with the square-cube law either. People often see characters in movies jump of bridges to land safely in water that is a hundred feet below them, not realizing that that is wildly impossible, as hitting the water from that height would seriously injury you. Most people don't need these things spelled out, because they either accept them, or realize "oh, it is a fantasy game."
And seriously? You want me to believe all you are advocating for is that we call the supernatural supernatural? We have. You then insist we justify WHY we can call it that, because the fighter doesn't have a supernatural bone in its body according to you, despite that being proven false again and again. Or you turn around and say "But those people don't want it to be supernatural!" when we finally say "fine, let's rewrite the fighter then". You are advocating for anything that grinds this conversation to a halt.
