Everyone has different opinions on what is "right" for parenting and what isn't. That's fine, but the problem comes when other people force their opinions on what is "right" onto other people and use the "For The Children" defense.
For example, many people these days believe that physical punishment is wrong, to the point where even those who believe it is right are hesitant to use it because they don't want to get charged with child abuse. There are places where it is more leeway - if you go to a more religious area, or are part of a more religious social circle, the occasional spanking for bad behaviour is far more likely to be accepted than if you were in a more secular social circle (or a different variety of the same religion; Evangelical vs United, for example). And there are places where even raising your voice at your child may be grounds for Child Services to be called.
As it is all done for the "good of the children", it becomes far more difficult to fight back against it when it's being applied to you. When your "right parenting" is "wrong parenting" to someone else, all they have to do is to call the local Children's Aid Services or Police or whatever the local name is and your life will never be the same. You may believe that spanking is fine, if done in moderation and is controlled but if your neighbour believes that any form of physical punishment is dangerous, you aren't going to spank your child. It's not about you wanting to coddle your kids, or about not wanting to hurt their precious feelings - it's about being terrified that you're going to be labelled a child abuser because you spanked them for breaking a flowerpot through a glass table when you have told them for months not to touch either, have given them time-outs when they touched them in your sight and the moment you're out of sight for just a few minutes, they do exactly what they know they aren't supposed to do.
Mrs. Makt and I were both raised by parents who spanked us when we deserved it, and our parents were quite good about explaining to us exactly why we were being spanked and what we could do in the future to NOT be spanked. But we're also both quite secular and non-religious, so our social circle does not condone spanking nor will the public schools we will send our child to. So we aren't going to spank Lil'Makt. Not because we don't believe spanking is right, or because we just want to coddle Lil'Makt, but because the cost of spanking may be far too high for the potential reward that will come from spanking (that reward being better behaviour from Lil'Makt, when required). It's part of the reason that we waited so long to have kids - we're scared of other parents, we're scared of schools with a "Zero Tolerance" policy ("Lil'Makt has a black eye... she says she was wrestling with Daddy and got hit in the eye. But it's right there on her face, so we have no choice but to call the Police.") and we're scared that if it comes to it, we'll lose Lil'Makt because the authorities will say "Better safe than sorry." and will take Lil'Makt away.
(Much of that is buying into the Media Hype surrounding the issue, we know, and that's a big part of what allowed us to make the decision to have Lil'Makt. But the hype does have a basis in reality, unfortunately.)
