To spank or not to spank

Spanking is a good way to educate children but there are other ways to do it.
To spank could be good to educate our children but it has limits. People in the last century practiced it with their kids and there were no laws to protect them, now there are laws.
However, there are many cases everyday of hurt kids by their parents that hit them when they lose control creating a violent environment and not teaching what is bad or good.
People should begin to talk with their kids instead of hitting them, they are human and they understand if we explain clear but we have to change our culture.
