most of the Christian holidays are based on ancient Pagan holidays:
Christmas is based on Yule, or Winter Solstice). Easter got its name
from an ancient goddess named Ostara, who represents new beginnings and
fertility; i.e. bunnies, at Spring Equinox. When Christianity came
along and tried to convert the old religionists to the "new" religion of
Christianity, the people were either forced to convert or were killed.
These societies were matriarchal, and worshipped goddesses above gods.
Do a little research;, you might learn something. Don't call a society
backwards because they worship a goddess. There are many
Pagans/Wiccans/Witches who honor goddesses as well as gods.
