I happily pay child support for the welfare of my son (I also provide his health insurance, happily as well) and would, even if the courts didn't require me to do so.
That being said, I can understand some of the anger behind keef spoon's rant. The judicial system is INCREDIBLY unfair to the dad, especially those who actually are pretty damned interested in being a real parent.
I'm not going to delve too deeply into my personal details, although Rallen13 could certainly vouch for my committment and heart as a parent.
