Why were the enlightenment ideas dangerous to Louis xvi?

The Enlightenment ideas emphasized reason, individual rights, and skepticism of traditional authority, which posed a direct challenge to Louis XVI's absolute monarchy. These concepts encouraged people to question the legitimacy of royal power and demand democratic reforms, undermining the king's control. Additionally, the promotion of liberty and equality inspired revolutionary sentiments among the populace, ultimately leading to the French Revolution and the king's downfall. Thus, these ideas threatened not just his authority, but the very structure of the monarchy itself.
