Is grown women calling their fathers "Daddy" a sign of unconscious submission to patriarchy?

77. The use of the word "Mommy" is actually more intriguing

The use of the word Daddy is pretty common in the South/Southwest, but even there my impression is that the word Mommy is dropped sooner and more widely in favor of "Mom."

So why is that?

My own guess is that using Daddy is not as much of a threat to the adult ego, whereas using Mommy is much more closely associated with young dependent children. It's Mommy who takes cares of you, wiping your bottom, spoon feeding you, kissing your scrapes. There is more urgent need -- especially for boys -- to distance themselves from infantilism as embodied in their relationship with their mother.

For all that the OP is trying to associate "Daddy" with acts of submission and deference, I think the truly emotionally loaded term is "Mommy" instead. Apparently, adult children can more easily express vulnerability with their father than they can with their mother.
