You have to admit the fallen angel thing, is very distasteful, and it IS very distasteful. So distasteful, that Julius Africanus, decided to change it. I believe the language is pretty clear, as you already pointed out. It’s not a salvation issue, so I don’t worry about it much, but I believe the sons of God, were fallen angels.
And people who come to Jesus using those tasteful re-translations might find that their Salvation isn't exactly Biblical.
