Your argument all along is that the WORD "People" was not in this verse and now you have conceded that it is.
REMEMBER what I have repeatedly warned you about:
Cherry-picking is NEVER a good idea - whether it's from Scripture or from scholarly sources.
Here is the consensus of scholarly thought on Matt. 25:32 . . .
Vincent's Word Studies
“All the nations” ( πάντα τὰ ἔθνη )
The whole human race; though the word is generally employed in the New Testament to denote Gentiles as distinguished from Jews.
“Separate them” ( αὐτοὺς )
Masculine, while the word “nations” is neuter. “Nations” are regarded as gathered collectively; but in contemplating the act of separation the Lord regards the INDIVIDUALS.
Benson Commentary
Matthew 25:32-33. Before him shall be gathered all nations — That is, all the INDIVIDUALS of all nations and ages;
Gill's Exposition of the Entire Bible
And before him shall be gathered all nations..... That is, all that have professed the Christian religion in all the nations of the world, whether Jews or Gentiles, high or low, rich or poor, wise and foolish, such as have had greater or lesser talents; though it is also true of every INDIVIDUAL of mankind of every nation, tribe and family, of every sex, age, and state, etc.
Coffman's Commentaries on the Bible
The cataclysmic and simultaneous judgment of all nations depicted here should not be understood as some special kind of selection regarding earth's governments. The "all nations" here is the same as that of the Great Commission (Matthew 28:18-20) and, from the parallel account in Mark, it is learned that it means "EVER CREATURE," that is, "EVERY MAN born into the world." Paul said, "We must all appear before the judgment seat of Christ; that each one may receive the things done in the body, whether it be good or bad" (2 Corinthians 5:10).
