I was only spanked once or twice and I don’t think it affected me.
But that was then. This is now.
Many rabbis have said human nature has changed and spanking no longer works in improving behavior. Instead, it just makes them worse.
This is supported by modern psychology; a number of studies show spanking makes children more aggressive, violent and angry over the long term.
It may seem absurd for the Israeli government (I think it was a court decision) to ban spanking.
But Rav Shalom Arush explains that since spanking is no longer effective, Hashem arranged for it to be illegal to take this method of discipline away from us.
