Why are there so few of us?

Given that there are 700,000 divorces in the US each year, and given the gross distortions of justice that several web sites report on every day, why are there so few blogs from men fighting to remain fathers? Is it fear? Exhaustion? Apathy? Or are there just very few suffering this fate? I can't believe this, as just in my own direct experience I know of multiple cases where fathers have been treated with gross unfairness. There must be more, why don't they write?
