Virgin birth is a fairytale
so is:
The tower of babel
Noah's flood
Adam & Eve
also
the Illiad
the Quran
Rig Veda
Zend Avesta etc.
But before you have a bird
These are my opinions not facts.
Everyone has opinions and they should be respected
If one's saying that the Adam & Eve story is a fairytale the so be it.
If one has to go overboard to such a statement, to me, it would seem that the offended one's faith isn't very strong to begin with.
