Given some of the dancing that has been portrayed in movies in recent years and imitated on dance floors, you are partly right. But not all dancing is "dirty dancing." Folk dancing, square dancing, ballroom dancing, and even many modern forms of dancing are not. Although you were advised against immoral dancing, what you were taught unjustly condemned all dancing. Keep in mind that the Bible shows dancing can be an expression of joy. The women of Israel danced after they crossed the Red Sea (Ex 15:20), and David danced before the ark of the covenant (2 Kgs 6:12-17).
