Kissing in the Public, do you approve?

Re: Kissing in the Public, do you approve?

Whats the big deal as long as they are not going all gaga over each other? A light peck on the cheek, holding hands, hugging doesn't hurt anyone. I support PDA.
I like the Iranian society in this regard. Unlike here, where people suffer from
"Aap ki bhabi" syndrome (instead of introducing as my wife), I found couples, aged as well as young (crossing the streets, sitting in the gardens, shoppin in the bazaars) holding hands and showing affection towards the other.
