I'm not sure I see the misuse. I see a lot of not-enough-context examples, but no clear misuse.
Also, the tropes aren't unrelated. Who Would Win
is a very common discussion topic (if not the most common) that often spirals out of control. This isn't exactly a supertrope, but there's a lot of overlap.
Now, Hypothetical Fight Debate
, on the other hand, seems to be a direct subtrope of Cavemen vs. Astronauts Debate
, in that it's specifically about fights. It's really The Same but More Specific
, though there is a pattern for that exact type of topic being common enough for its own pattern. This also means all fight discussion examples on Cavemen vs. Astronauts Debate
should be moved to the subtrope.
It's not misuse to list things on the supertrope, but it's standard practice to only list things in the subtrope, unless (and this is my opinion) the same work also features several subtropes to the same trope. I'm guessing there just was a failure to move those examples when the subtrope was launched, rather than this trope gathering misuse since that.
