This complaint is hardly a new one. I direct you to this passage published in 1816 in The Times of London:
The indecent foreign dance called the Waltz was introduced … at the English Court on Friday last … It is quite sufficient to cast one’s eyes on the voluptuous intertwining of the limbs, and close compressure of the bodies … to see that it is far indeed removed from the modest reserve which has hitherto been considered distinctive of English females…[Now that it is] forced on the respectable classes of society by the evil example of their superiors, we feel it a duty to warn every parent against exposing his daughter to so fatal a contagion.
The waltz is a “fatal contagion?” Harsh, dude.
