I think that one of our great advances is that people now can honestly say "I won't be a parent...I may beat my child to death". Instead of the old world attitude of "It's my duty to have kids, no matter how crazy or evil I am".
Granted, I have a darker view of life and the world. I also know that most predictions I hear and read rarely come to fruition. :)
Just because they're birthin' like bunnies doesn't mean that all their rabbits ain't crazy.
Some folks who say that are honest ... and many are making excuses. Raising children properly isn't easy.
