Per Isaiah 2, "the Lord alone will be exalted in that day" (the DotL). This can hardly be said to be true when the AC is commiting the GT and is overcoming the entire earth.
1) the 7-yr / 70th Week (judgments unfolding upon the earth--the "IN THE NIGHT" aspect);
2) His/Christ's Second Coming to the earth (the "SUN of righteousness ARISE" aspect); AND
3) the ENTIRE MK age (1000 yrs--the "reign... GLORIOUSLY" aspect)
... so depending on CONTEXT, each passage speaking about this must be examined in its own wording as to WHICH ASPECT the particular passage is focusing in on. Not EVERY passage covers EVERY ASPECT (of "the DOTL").
Your making my point for me, the tribulation spoken of is a general tribulation that all will experience. If it's been going on for 2000 years, it can't be explicity tied only to the 70th week. When do you see the 2000 supposed years ending, 2033? 2000 years after the birth of the church?
--The "false claim" was NOT referring to "His Second Coming [to the earth]" but the "[period-of-time-of-]JUDGMENTS unfolding upon the earth" ASPECT OF "the DOTL"--what we commonly label "the Trib" or "70th Week"/"7-yr period"]. So Paul is addressing THAT FALSE CLAIM in 2Th2, basically saying "Not so!' and WHY!)
By re-defining terms, and by grammatically SMOOSHING TOGETHER parts of sentences (which are speaking of DISTINCT THINGS), is how people completely miss what it is that Paul is actually conveying in this 2Th2 passage... and quite commonly I might add.
As to your second point (or question) in that section, my answer is: that it is actually told us in the TEXT ITSELF (of Hosea 5:14-6:3)--did you read the text?, where (when speaking contextually of Israel) it says / He says, "I will go and return to My place, TILL [they acknowledge their offence, and...]..."--this would refer to the year of His ascension (as to what the "after 2 days" is in relation to, regarding them). I believe only "32ad" FITS all of the criteria scripture itself supplies. For example: the "69 Weeks" concluded on what we call Palm Sunday (when He SAID the words in Lk19:42-44 (about "the CITY") and DID the Zech9:9 thing (ALSO about "Jerusalem"--note: this is WHAT the Daniel 9 prophecy itself SAYS it is about: "AND UPON thy [Daniel's] holy city")... only 32ad has the proper amount of months / moons between, regarding when "the GOING FORTH of the decree to..." would have taken place. (33ad has problems, in that regard.)
So, where it says in Hosea 5:15 "I will go and return to My place, TILL" and then says, "in their AFFLICTION / TRIBULATION [LXX; G2347] they WILL seek Me early/earnestly"... (after TWO days)... it is specifically NOT talking about the tribulationS that the church of Thessalonians were ongoingly experiencing (2Th1:4), nor to what "the Church WHICH IS HIS BODY" has been (and will) throughout its entire existence on the earth since the first century... but is speaking specifically regarding Israel and the timing of THEIRS (perhaps think: the time of JACOB'S trouble... That'll be "7 YEARS" [whereas ours has taken place over/throughout some near-"2000 years"--NOT the same thing, see
That's all I have time to address, at the moment. Hope that helps you see my perspective.
