Evidence for that? Its total nonsense. "Angel of the Lord" SIMPLY MEANS an angel of the lord, a messanger of God ... there is no indication that the angel is the massiah ...
Also bowing down ISN'T worship ... people do that to King David in the scriptrues (using the same word, such as Abigail), doesn't mean they thought that King David was Yahweh, it's also use for simply the title of King in Israel .... It doesn't mean religious worship necessarily.
In the Greek (used in the septuagent as well) preoskeneo, sometimes translated worship sometimes translated obescence, is used for kings, angels, saints, God, Jesus, preists and so on.
But the word Latreuo, which is religious worship is ONLY EVER used for YHWH, the father.
That whole post is simply a missunderstanding of the language. If "worship" or "obescience" makes the angel of the Lord (which is just a title for an angel, which could be many different angels), makes that angel Yahweh himself, it also makes king david yahweh.
