@prouddaughter,
My opinion is doing so or feeling the need to do so is sad and that is the same as half blacks who pass as whites.
In either case your background that you share with the world is up to you an no one else.
Footnote I have had two lovely step daughters who was half and half both earn master degrees but I have no clue what they put on their forms concerning race.
They both end up marrying white men if that mean anything.
