Why do people not know about god's consort/wife/whatever?

The knowledge that the Hebrew God El originally had a female counterpart is a little known fact to modern Christians as the male dominated patriarchal Roman Catholic Church throughout it's history has attempted to destroy or demonize any and all evidence or references to a prior female Deity. However in the temple of Jerusalem she was known for many centuries as the Virgin Wisdom, the Queen of Heaven and also referred to as Anat, Asherah, Mari or Mariam and many early Israelite chieftains called themselves her sons.
