WWE is a soap opera, not a sport. There are impressive feats of athleticism/death defiance (Shane O Mac jumping off a 20 ft cage, etc), but nobody over the age of 6 thinks for a minute it’s actually a real competition.

Yeah, maybe.
Not sure what this has to do with US reputation . . .
If you're interested in (still fake but) more technically grounded performance look into Japanese puroresu.
