I guess at the end of the day it is all about compatability and what suits you. If you are older and fall for a beautiful Filipina then it is all good. The thing is that we all judge without knowing.
My wife often says to me when we are out that she can hear whispers of people saying about 'oh look at her with her white boyfriend' which makes me laugh as no one knows we are married. We publiclly show affection for one another, which doesn't seem to be the 'norm' But then when we are out with our son, the whispers stop and the coo'ing starts when they see us all together.
My wife is 16 years younger, but really.. who cares.
The example I gave of Anna Nicole Smith was more than probably a gold digging act, seen by the western world as something abhorrent. Stereotypically, we judge everyone without knowing it. But we all have needs and it's no one elses business if we find happiness/love with someone of a different age.
But if I had a daughter, I maybe I would like to give my opinion to think about her actions.
