I totally feel for all the Dads here as I am experiencing a similar situation and am taking action to help make change truly for KIDS benefit & hence our future. So:

1) WHY is this prejudice still existing in most countries family court systems if its so obvious ? What or Who are the obstacles?

2) WHO is responsible for making the change we all talk about ?
Hence how do we get to them to speed up change?

3) HOW should we gather WHAT type of "proof" of the other parent (mums usually) manipulating & alienating that is useful in court ?
