And is our fundamentalist theology truly Biblical? In particular, there are many divergent views on this forum as to Biblical theology. I reject the idea of the reestablishment of the state of Israel as a physical nation in the land promised to Abraham. Such doctrines have no basis in the teaching of Jesus & his Apostles, so indicate apostasy. [Please don't argue the case on this thread - there are plenty of others!].
Then you shouldn't make an inflammatory statement and then proceed to tell us to shut up about it.
Having said that I disagree with your premise that "the reestablishment of the state of Israel as a physical nation in the land promised to Abraham" qualifies as a doctrine worthy of the apostasy (falling away).
The core doctrine of concern relative to the apostasy:

7 For many deceivers are entered into the world, who confess not that Jesus Christ is come in the flesh. This is a deceiver and an antichrist.
8 Look to yourselves, that we lose not those things which we have wrought, but that we receive a full reward.
9 Whosoever transgresseth, and abideth not in the doctrine of Christ, hath not God. He that abideth in the doctrine of Christ, he hath both the Father and the Son.
Whoever denies that Jesus Christ is deity come in the flesh as a mortal human being, true God and True man is of the Antichrist.
The biggest problem: the tares, who have learned the words to repeat this central issue of true Christianity but 1) Infiltrators who do not believe it in their heart or 2) Know it is true but hate Him.
So in my 50 plus years of walking with the Lord it is evident to me that there are many who are able physically to bow the knee but not the heart to our great God and Saviour Jesus Christ.
Among them IMO are a few true believers who for fear will not depart from satan and one day there will be a sorting out
Matthew 13
49 So shall it be at the end of the world: the angels shall come forth, and sever the wicked from among the just,
50 And shall cast them into the furnace of fire: there shall be wailing and gnashing of teeth.
Matthew 25
31 When the Son of man shall come in his glory, and all the holy angels with him, then shall he sit upon the throne of his glory:
32 And before him shall be gathered all nations: and he shall separate them one from another, as a shepherd divideth his sheep from the goats:
33 And he shall set the sheep on his right hand, but the goats on the left.
34 Then shall the King say unto them on his right hand, Come, ye blessed of my Father, inherit the kingdom prepared for you from the foundation of the world:
...
41 Then shall he say also unto them on the left hand, Depart from me, ye cursed, into everlasting fire, prepared for the devil and his angels:
So, concern about the apostasy, of course. Panic - no.
Matthew 16:18 And I say also unto thee, That thou art Peter, and upon this rock I will build my church; and the gates of hell shall not prevail against it.
