He can defend all that he wants, what cannot be defended is the fact that she released the worst song of the album as single, like what the hell was she thinking?
But the thing is Madonna has been trying to push buttons for 30 years. When people see her being sexual, they don't see her trying to represent a woman's sexuality in her 50s. They see someone who is seeking attention and headlines through sexuality. This is literally how Madonna's career began with Like a Virgin. People caught onto her tactics 25 years ago.
Caitlyn has received criticism for dressing too young, just not as much as Madonna for various reasons. I think most people are more shocked that Caitlyn was Bruce and looks so unexpectedly good that it directs the attention away. The age discussion is not the big topic so its tossed aside. Also people understand Caitlyn has wanted to be a girl her whole life and has had to go 65 years not being able to. Madonna doesn't have that story to sympathize with.
