An extraordinarily good counterpoint to the case before us. I think the key here is that a particular viewpoint from a man can be apparently more revealing, eg "this guy is on the inside and he said ...". If the same ideas are presented from a woman as a speculation then they are less interesting, eg "this woman is guessing that this is what men talk about when they're with other men ...".
A painting is not just an image (as the curator in the link above claims) but is also an expression of the artist themselves (in most cases for non-professionals who actually paint their own work). A painting with the foot has a different quality to one painted by hand because one knows how the artist struggled against a physical adversity, etc..
