And a child would know this how?
By being told by whom?
At what age?
And the child, in a world where this was normal would care why?

The only indication that this child would have that it wasn't normal would be someone such as you trying to make the child uncomfortable.

No different than people making children with dark skin or whose parent is divorced, or who was adopted feel less worthy. You might want to consider your attitude as being nothing more than pre-prejudice.
