Miriam did not protest against Moses, she protested against God, who appropriately spat in her face. God was her Father. God's humiliating custom of spitting in faces has continued to this day and it is described in the Book of Revelation. God will soon spit in the face of His lukewarm end-time bride-to-be (or Church) (Revelation 3:16). Her offensive behavior is not that she stands up to leaders, but that she does not stand up to leaders. By the way, Miriam was a racist and an ego maniac, so she deserved to be spat upon for more than one offense.
