Both men and women should be troubled by representations like this.  It is insulting to men, of course. But representations of men as childlike also contributes to the idea that men cannot be held responsible or accountable for bad behavior.  As I have explained elsewhere on this blog:

So long as we buy into the idea that we can’t expect men to be good partners or fathers, we will tolerate women’s responsibility for the second shift and their placement on the mommy track at work.

This extends, too, to not coercing women sexually, not cheating, and being partners and lovers who give as much as they receive.

This portrayal of men as children, idiots, animals  (see here and here), and monkeys perpetuates patriarchy, even as this perpetuation is disguised by the denigration of men.
