I think that society needs to stop believing the idea that upon the separation of two parents the mother is automatically and unquestionably the parent that should be the person best placed to primarily care for the child and to decide and dictate how the relationship between child and father.
Logistically, the child may spend a little more time with the mother but mothers and fathers have so much to offer in different but equal measure that one parent's 'rights' should never trump that of the other parent.
I can understand why people support a presumption of 50/50 being a starting point for arrangements upon separation as it would prevent cases where a parent may have to fight for 'contact'.
But I can see why such a presumption may not be the panacea that those who support it think it would be.
In my own experience, regardless of the emotional and financial pain I have had to endure, and even though the situation was all due to my ex wife's terrible behaviour, I always fought for the relationship with my child and not 50/50 time rights and fortunately this has worked for our child who now naturally lives fairly equally at mum and dads.
The sadness in this case is that the mother couldn't bear for her child to have a loving relationship with the child, even though she could no longer have a living together relationship with the child's father.
And the result is what is happening now, when a parent hates the other parent more than they love their child.
