I find this especially hilarious because i'm pretty sure that 50 and 100 years ago in the U.S., a man wasn't considered a man unless he could dance. ...and that didn't mean just jumping around at a club -- it meant knowing specific dances and how to lead them.

...and i'm pretty sure that within most Western societies and many Eastern, Native American and African ones, this has also been true for most of the past 1000 years or more.

In short, yes, you should know better. :)
