I know exactly what you are saying regarding women getting away with a LOT more, first hand unfortunately.
It's only been two years for me and 11 visits to the court, but my ex is just as guilty as this mother of trying to poison my children's minds. Fortunately I still get to see them a bit after winning all of these battles. They would be way worse off if they didn't get to see me at all, like this father, for seven years.
I will get sole custody by this summer (my ex's crazy actions have guaranteed that, but she still has her right to make it go to trial). Men have a right to go to trial but unless the woman is nuts they don't get the kids.
The Judges have sped up the whole process for me and the kids. But still, much more can be done to reward good dads. The first important step, IMO, should be that mom AND dad are both considered to be fit parents. If the mother is "better" than the father let it be proven, rather than ASSUMED, like it is now.
That's gotta be worth at least four cents.
