I disagree totally with the premise that there is something wrong with irate commentary concerning pedophilia vs. parenthood.
I can't even put those two thoughts into the same breath, they're so totally foreign to each other.  Truly, I can't comprehend how you can connect them at all.
Nope...while I agree that truly bad parenting can have hugely negative impacts on a child, and should be dealt with very harshly (depending on the nature, even as harsh as pedophilia), I simply cannot subscribe to this idea.
Pedophilia and Parenting?  You've left me in the dust on this one.
To suggest that a bad parent is actually worse than a pedophile?  Our philosophies totally part company here...
Besides, bad parenting runs a very broad spectrum from mild neglect to outright abuse, exploitation and abandonment.
Pedophilia has no spectrum...hideous from beginning to end.  Period.
PS:  We do agree on the core concept though.  Do. Not. Hurt. Babies.
