Christians believe that all of us who were baptized into Christ Jesus were baptized into his death and that we were buried with him through baptism into death in order that we too may live a new life. We also believe that those of us that were baptized into Christ have clothed ourselves with Christ. Why don’t you believe that?
This is only true if one is a believer obviously. Does a baptized pagan become less of a pagan? Being baptized into Christ means one has received Christ. An infant cannot receive what he doesn't even know exists. Clothing your self is an action verb.
"put on the Lord Jesus Christ, and make no provision for the flesh, to gratify its desires."
" you who are younger, be subject to the elders. Clothe yourselves, all of you, with humility toward one another, for “God opposes the proud but gives grace to the humble.” Humble yourselves, therefore, under the mighty hand of God so that at the proper time he may exalt you,"
It's something we do in our hearts first, the water is only an outward sign of what we have done, that is humble ourselves to receive him.
The very verse you quote confirms what I said, if you quote the whole thing.
26 So in Christ Jesus you are all children of God
through faith, 27 for all of you who were baptized into Christ have clothed yourselves with Christ.
No faith equals no reason to be baptized. An infant can't be said to have faith in what he can't understand. And what about the people who believe that infant baptism saved them and then go out and live for the devil? They are under a delusion that could cost them their soul.
