"Preterism is a Christian eschatological view that interprets some or all prophecies of the Bible as events which have already happened. This school of thought interprets the Book of Daniel as referring to events that happened from the 7th century BC until the first century AD, while seeing the prophecies of Revelation as events that happened in the first century AD. Preterism holds that Ancient Israel finds its continuation or fulfillment in the Christian church at the destruction of Jerusalem in AD 70." Wikipedia
Preterism is gentile envy of God's choosing of Israel.
It is rebellion against His covenant faithfulness.
It paints a picture of a God who is weak and unable to keep His promises.
It calls into question the ultimate faithfulness of Israel's Messiah to fulfill the prophecies associated with His calling.
It refuses the God ordained position of Ham and Japheth, which is to serve the chosen people and bow to enter the tent of the chosen people.
It reeks of the very arrogance that Paul warned about in Romans 11.
