'scholar':
Too easy. The structure of the narrative as recorded in the Olivet Discourse shows that the timing of the Great Tribulation is associated with the ;chosen ones' so it would appear that such an activity including that there would be false prophets that would attempt to mislead those same chosen ones would occur not at the beginning of the Parousia but rather towards the end of the Parousia.
Nope. No Bible citations to be found there. You have provided speculative commentary about an interpretation that contradicts the plain reading of the relevant scriptures.
What the Bible does say is that the "false prophets" (for which you are a fine allegory) would be claiming that 'Christ' would appear before the end of the 'tribulation', whereas Jesus is quoted as explicitly saying his 'presence' would be after the tribulation. (Matthew 24:15-31; Mark 13:14-27).
