For me it's a yes and a no. YES if your the parent( a mom or a dad ) to the baby . It's natural for a parent to kiss them that way.
And NO for just any adult, specially when children come to an age wherein they know the difference from a kiss on a cheek to a kiss on the lips. Kids these days grow so fast that even us as parents they don't want expression of love,hug, kiss in public.
I think it comes down to habit and how you were raised. I think it is ok to kiss children on the lips. If you raised your child by kissing them on the lips since they were a baby, you may continue that behavior their entire life and I do not see anything wrong with it.
Kissing and hugging our children how much we truly love them. Taking it one step further, I think it is ok to kiss close friends on the lips as a form of greeting. I am Italian and we tend to be affectionate when we greet people.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
