Parental Alienation

I know what this is, I had an ex-wife who decides she was going to cut me off from my children.  I do not know why the court system favors mothers over fathers, I think they should look at who is the better parent.  Sometimes Father is more nurturing than mothers and sometimes Mother is Nurturing to fathers.  I think the facts should judge who is a better parent, fathers go into court with the idea they will be lucky to get 50% custody.  The system should base it on facts

because the system took my kids, I have not talked to my son for four years and my daughter for three, how is that fair? If I choose to be in their life, I should be able to be in their life
