Why it's safe to reject the idea that Jude is evidence for "demon/women sex" in Genesis 6:
1. Jude highlights a list of different sins,
not just sexual sin.
2. Demanding that the context of verse 6 must be verse 7 is
purely subjective: why not verse 5 or 4?
3. Jude's mention of "Sodom and Gomorrah" refers to
homo sex - not hetero sex - which is irrelevant to Genesis 6.
4. The only connection between verse 6 and 7 that can be safely drawn has to do with the
future fiery destruction
awaiting fallen angels (verse 6) that is exemplified by the
past fiery destruction of Sodom and Gomorrah (verse 7).
Again, if you're going to rigidly tie the
homosexual immorality of Sodom and Gomorrah in Jude 7 to the fallen angels of Jude 6,
then to remain consistent you'll have to say the sex that took place between angels and women was homosexual sex, as well...which the only giant offspring possible would have been helium balloons in Antediluvian gay pride parades
