If dancing will largely prevent you from having interesting conversations, it may well be an antiskill—but if you go to a lot of nightclubs where loud music makes conversation difficult, knowing how to dance seems very useful indeed!
This seems like a poor example—why go to loud nightclubs if not to dance, conversely knowing how to dance increases the chance that you’ll choose to go to loud nightclubs. The benefits and drawbacks of dancing are similar whether the music is loud or soft. It only makes sense if you were dragged to the party and had to make the best of it.
I think a better example would be martial arts—there are situations where knowing martial arts could get you into a ton of trouble (eg some gang wants to beat you up as a show of dominance, but with trained instinct you manage to hurt one of them), and others where it could save your life. As a more mundane example, knowing facts about politics seems to polarize people by allowing them better motivated skepticism of opposing viewpoints.
