Why did Paul command us to "GO BACK" and look at our examples (I Cor 10:11) for doctrine yet 'Christians' don't (I Cor 11:1) for baptism?

Update: IN WHICH >>>NO ONE GOT WET<<< (EXODUS 14:16;22) AND THE LORD'S SUPPER

IN WHICH ALL "ATE SPIRITUAL MEAT AND DRANK SPIRIT DRINK" (I CORINTHIANS 10:3-4)?
Update 2: CORRECTION: "SPIRITUAL DRINK." "THE CUP OF BLESSING WHICH WE BLESS IS IT NOT THE COMMUNION OF THE BLOOD OF CHRIST? THE BREADH WICH WE BREAK, IS IT NOT THE COMMUNION OF THE BODY OF CHRIST? FOR WE BEING BEING MANY ARE ONE BREAD, AND ONE BODY: FOR WE ARE ALL PARTAKERS OF THE THAT ONE BREAD"... show more CORRECTION: "SPIRITUAL DRINK."

"THE CUP OF BLESSING WHICH WE BLESS IS IT NOT THE COMMUNION OF THE BLOOD OF CHRIST? THE BREADH WICH WE BREAK, IS IT NOT THE COMMUNION OF THE BODY OF CHRIST?

FOR WE BEING BEING MANY ARE ONE BREAD, AND ONE BODY: FOR WE ARE ALL PARTAKERS OF THE THAT ONE BREAD" (AKA CHRIST WHO IS SPIRIT; I COR 12:13) (I CORINTHIANS 10:16-17)!
