Your missing the point my friend
The Man Of Sin/The Beast seen below hasn't been revealed anytime in history, nor has Jesus Christ destroyed this figure by the brightness of his second coming, this literal figure hasnt been seen anytime in history, this is a future event, unfulfilled.
Historicism denies a future Man of Sin/The Beast, as they falselyteach this took place in the 1st century, Historism is wrong in false teaching.
2 Thessalonians 2:3-8KJV
3

except there come a falling away first, and
that man of sin be revealed, the son of perdition;
4 Who opposeth and exalteth himself above all that is called God, or that is worshipped; so that he as God sitteth in the temple of God, shewing himself that he is God.
5 Remember ye not, that, when I was yet with you, I told you these things?
6 And now ye know what withholdeth that he might be revealed in his time.
7 For the mystery of iniquity doth already work: only he who now letteth will let, until he be taken out of the way.
8 And
then shall that Wicked be revealed, whom the Lord shall consume with the spirit of his mouth, and shall destroy with the brightness of his coming:
9 Even him, whose coming is after the working of Satan with all power and signs and lying wonders,
