Maybe it's you who should look up the term "self-defense", because comparing that to hitting your kids is ludicrous. Please try again.
Chausette, with respect I am asking you to please consider my post objectively.
It's not that I'm comparing spanking with self-defense, or beating your child to murder. No, that is not it. The point I am trying to convey is that you are broadly generalizing two strikingly different things. You consider spanking and beating to both be bad because, with a very huge and non-discerning brush, you consider them both as "hitting kids." It's the same as saying both self-defense and murder are wrong because it's "killing people." Or that John and Hitler are both bad people because "they eat their veggies."
The error in your logic is a faulty comparison. You have not considered all of the variables.
