What does the "Curse of Noah" in the book of Genesis 9:18-29 mean, and why is it considered significant in the present day?

In the book of Genesis 9:18-29, we see a scenario that has perplexed and confounded scholars and laymen alike. In this chapter and verses we see Noah, the patriarch, and the prophet that oversaw the building of Noah’s Ark, act rather inappropriately. He decided to plant a vineyard as a vocation, and sometime later became intoxicated with wine. He then fully undressed himself in his tent, (namely “galah,” in KJV Bible lexicon; it means to “strip down” in an inappropriate manner) and as the Bible reports, began acting in a vulgar and disgraceful manner. His youngest son, Ham saw this scene, and went out of his Father’s tent and announced the scene publicly (“Told his two brothers without,” this means “told his two brothers out in the open” in Bible lexicon). Japheth and Shem then went and got a garment and put in on their shoulders, and walking backwards, laid the garment on their Fathers body so as not to see his nakedness. After waking up from his stupor, Noah, knowing what Ham had done, “The Bible does not indicate “how” he knew,” proceeded to angrily curse the descendants of Ham, and bless the descendants of Japheth and Shem. Among the curses given to the descendants of Ham, is that they would be the “servants of servants,” which for all intents and purposes made the descendants of Ham beneath their cousins hierarchically. This curse is in many respects the go-to verse for people who look to justify slavery, and other historical atrocities from Biblical perspectives. The Bible lists the nations of the world that descended from each of Noah’s sons, and as it turns out, the nations that descended from Ham, are many respects war-torn, and impoverished nations even to the present day. This verse is significant because it has mysterious coincidences to the state of the world in the present day, and it has to do with various nations and peoples. The book of Galatians 3:13–14 however, shows the negation of all curses presented in Genesis. “Christ hath redeemed us from the curse of the law, being made a curse for us: for it is written, Cursed is every one that hangeth on a tree: That the blessing of Abraham might come on the Gentiles, (non-Hebrews,) through Jesus Christ; that we might receive the promise of the Spirit through faith.” This verse is significant, because it shows that the seed of Abraham, namely the Israelites, of whom the law of Moses was originally presented to, are no longer the sole heirs of the blessings of God. This verse further indicates that Biblically, Jesus Christ was the fulfillment of all Old Testament prophesies and the was the end of all Old Testament curses, and traditions in relation to their necessity for salvation. This verse further indicates that all people on the earth are hereby free from the curse mechanism through the atoning sacrifice of Jesus Christ.
