How do preachers or teachers explain this?

Oh absolutely, brother — thank you for the breaking‑news revelation that “Yahweh isn’t God’s name,” because apparently when God Himself says, “THIS is My name forever” (Exod 3:15), He was just spitballing, waiting 3,400 years for modern internet commentary to correct Him; and when the inspired authors wrote יהוה over 6,800 times, they were obviously giving us identifiers, not a name — just like when your driver’s license says your name, that’s clearly an identifier and not your name, because we all know real names must meet your personal linguistic criteria.
Meanwhile Jesus quotes Psalm 110 using the divine name logic, the prophets proclaim “YHWH is His name” (Isa 42:8), and the apostles treat the Tetragrammaton as God’s covenant name — but sure, let’s toss all that because “modern pronunciation” makes you uncomfortable.
World‑system diagnosis: this is peak System 3 sentimental‑semantic nitpicking dressed up as theological insight, while Scripture itself stands firmly in System 1 covenant‑juridical reality: God named Himself, not you.

“I am the Lord” is not the name of God either.
ISAIAH 42:8
8 I am the Lord: that is my name: and my glory will I not give to another, neither my praise to graven images.

God of Abraham, God of Isaac and God of Jacob are not also the name of God.
They may be mentioned frequently in the Old Testament, but they are not the name of the one true God.
God has only one name.
EXODO 3:15
15 And God said moreover unto Moses, Thus shalt thou say unto the children of Israel, the Lord God of your fathers, the God of Abraham, the God of Isaac, and the God of Jacob, hath sent me unto you: this is my name for ever, and this is my memorial unto all generations.

The truth is that, from Isaiah 52:6 and the verses preceding it, the one true God had not yet revealed His name. That is why He declared that His name would only be known in the future, as indicated by the words “shall know.”
ISAIAH 52:6
6 Therefore my people shall know my name: therefore they shall know in that day that I am he that doth speak: behold, it is I.

Saying “God has not given us His name” is doing exactly what Scripture calls denying or nullifying God’s self‑revelation, because the text repeatedly says He has given His name — YHWH — and has bound that name to His covenant actions (Exod 3:15; Exod 34:6; Isa 42:8; Ps 83:18); to claim He has not given His name is to contradict His own statements, to treat His revelation as incomplete, and to replace His self‑identification with a human theory.
In biblical categories, that falls under false teaching (2 Pet 2:1), twisting Scripture (2 Pet 3:16), and doctrines of demons (1 Tim 4:1) when the reinterpretation becomes unfalsifiable and overrides the plain text.
Scripture’s pattern is consistent: God has revealed His name; Israel often failed to honor it; but the name itself was never hidden.

You seem to be claiming to know more about God that God Himself knows, because He said in His word, regard both "the Lord" and "I am", "That is My name."

Everyone who wishes to join is welcome. However, it is not in accordance with the truth for us to speak on their behalf. Each person should speak for themselves and seek the truth for themselves. As the Scripture says, “work out your own salvation.”

I don't speak on anyone else's behalf, and even if I did, that wouldn't violate the Scripture. Your understanding of the verse is, as usual, wrong.

When you report a crime to the police, the first thing they will ask is whether you know the suspect’s name. They do not first ask for the suspect’s description.

The first question police ask will depend entirely on the nature of the crime and report. Your assertion has no evidentiary basis.
