The point is: it's perfectly okay when the guy is older than the woman, but it is somewhat of a issue when the woman (either the actress or/and her role) is older.
But my point is that it's established in the movie
that he's older and is almost a plot point in the case of Raiders.
I'm not denying that there is
an element of hypocrisy. I'm just saying that Indy is a terrible example.
