I don't believe it was. For one, it would mean a huge percentage of the population has a schizotypical personality disorder, or avoidant personality.
For another, there is a strong cultural effect on dance popularity. There are areas where dancing is banned due to religious prohibitions. (The movie "Footloose" is based on that premise.)
While it's possible that, say, 0.01% of the people may not dance for reasons the OP gave, it's very unlikely that the OP's argument has any significance.
