So the words of the Lord are preserved from this generation forever.
Not "preserved forever", as you and all KJV-only proponents read it. That you all misread the text is rather telling.
Psalms 12:1-8
Help, LORD, for the godly man ceases! For the faithful disappear from among the sons of men. They speak idly everyone with his neighbor; [With] flattering lips [and] a double heart they speak. May the LORD cut off all flattering lips, [And] the tongue that speaks proud things, Who have said, "With our tongue we will prevail; Our lips [are] our own; Who [is] lord over us?" "For the oppression of the poor, for the sighing of the needy, Now I will arise," says the LORD; "I will set [him] in the safety for which he yearns." The words of the LORD [are] pure words, [Like] silver tried in a furnace of earth, Purified seven times. You shall keep them, O LORD, You shall preserve them from this generation forever. The wicked prowl on every side, When vileness is exalted among the sons of men.
Psalm 12 isn't about the kjv
It's the godly man that the LORD will preserve from this generation forever. See verse 1. The thing the psalm says is in need of preserving / saving.
It is His word to save him that is pure and proven by trials of fire. See verse 5. The actual thing God says in this psalm.
Y'all kjv-ists have this psalm all kinds of twisted, IMO
Because you have no context. You have pretext.
