The problem with your understanding is that, the weeds represent the wicked and the wheat represents the righteous. Therefore, when the harvesters/angels go throughout the earth, when they first gather the weeds (one taken) they will be gathering the wicked. Afterwards the wheat will be gathered, which is synonymous with Matt.24:31.
Also and as I previously pointed out and is unmistakable, is that the "one taken" is being compared to those who were "taken away" by the flood, which are also the wicked.
Just as the wicked were taken away in the flood, so also at the end of the age will the wicked be collected by the angels and brought back to the valley of Megiddo and killed by the double-edged sword. I'm not telling you this as something that is debatable, but a fact.
When Jesus said "one will be taken and the other left" and his disciples said "where Lord?" And Jesus said "wherever there is a dead body there will the vultures be gathered," how does that support the event the gathering of the church? It doesn't!
The fact that when the Lord returns to the earth to end the age as demonstrated in Rev.19:11-21 and sending his angels out to first collect the weeds at the end of the age. And the fact that at the end of the age there will be an angel calling to all the birds to come and gather themselves to the great supper of God to eat the flesh of those kings, generals, the might men, their horses and those who will have been taken by the angels, it would support the Lord's response when He said, "wherever a dead body is there will the birds be gathered."
"one taken and one left" is not the righteous and the righteous. According to the parable in matt.13, the harvesters/angels will "first" weed out of his kingdom everything that causes sin and all who do evil.
As far as people eating and drinking, marrying and giving marriage, planting building, etc., this will be the state of things just before the church is gathered, which is then followed by God's wrath, sudden destruction.
Your first thrre paragraphs have 3 premises
1) half the wicked are taken away
2)the tares are harvested at harvest time with the wheat still standing in the field
3) the wheat and tares analogy points to Armageddon.
All three are wrong.
There is no "wicked taken". in mat.( and especially any instance anywhere,where half the wicked are gathered).
The righteous are taken out. DELIVERED.
The wheat and tares are harvested TOGETHER. Then separated. Not meticulously cut while leaving the wheat standing.
Re read the story. A case is even made against the "leave the wheat standing" idea.
Further,the tares are burned. So it is NOT Armageddon. It is the GWT judgement.
Also,the taking out all things that offend is at the end of the millennium.
Ok,now,it is not fact ,as you say. It is debatable,as I have shown you conclusively that every component you brought forward is incorrect.
IOW,you began incorrectly. You began with the "body/vulture" dynamic. Then,you built on top of it.
That is the same mistake postribbers make when ascribing the last trump.
The only thing,as I see it,where your understanding would possibly work is at rev 14,where there is a gathering of wicked,before Armageddon.
THREE BIG PROBLEMS;
1) You guessed it,the RIGHTEOUS are gathered first
2) there is no " half the wicked taken"
3) the setting is a destroyed earth.
The one taken,one left component is not defined or understood through Jesus answer to" where are they taken".
The only plausible explanation is that Jesus was making a synonymous statement, like "red sky,branches,vine,winepress,fig tree,snake,bread"...and so on.
Vultures / bodies Armageddon = yes
Everytime = no
