Your citation of Luke 21:22 should be taken in context of verse 32. Together Jesus must be saying that ALL prophecy would be fulfilled in HIS generation.
There’s no end to the idiocy of such interpretations. I used to think it MIGHT be possible to reason with some of such rabid cliques. I was wrong. They are as rabid as the Roman Catholic et al rabid cliques . . . they MAY not be QUITE as UNBiblical but are clearly well along in that direction.
And their convoluted, mangled elastic “Bibles,” dictionaries and histories are definitely QUITE AS ABSURD.
