Agreed! However I think you have confused two different Scriptures.
Jude 1:6 ..........
"And the angels who did not keep their positions of authority but abandoned their proper dwelling-these he has kept in darkness, bound with everlasting chains for judgment on the great Day."
Nothing there about angels going after
"strange flesh" so that would in effect rule out demonic possision or sons of God co-habitating with the Daughters of men in Gen. 6.
There in Jude 6........."Who did not keep their proper domain" can also be translated, "who did not keep their positions of authority." It shows that God assigned them a stipulated responsibility, a set place, but they left it. The set place was on the earth. They mounted an attack against God in heaven. Defeated, they were cast down to earth, and the place that they were originally given as their domain instead becomes a prison, a place of restraint/chains. (
Revelation 12:3-4,9;
II Peter 2:4).
Jude 7 then is a "Comparative" Scripture to verse #6......
"Even as Sodom and Gomorrha, and the cities about them in like manner, giving themselves over to fornication, and going after
strange flesh, are set forth for an example, suffering the vengeance of eternal fire."
Just as sure as the angels who rebelled against God WERE judged and placed in chains....so will the HUMANS of Sodom and Gomorra who went after
STRANGE FLESH.
The Greek term....
ἕτερος (the lexical form of ἑτέρα(ς), meaning “other/another”) is transliterated as
heteros; - This is the exact opposite of what would be expected in this context --
ὅμοιος (
homoios, meaning “like, similar”).
So then the meaning is ----Homosexual.
