You come out of the house to do few things which you cannot do at home. Can't you Love/Kiss/express emotions at home? If you say that due to family environment you cant do it at home then you cant do the same in public too. First upgrade your family to 21st century and then think about upgrading your country. The ban is for couples doing it and not necessary that every couple is married. Looking into the past what has been going on in Delhi I feel this is good move. Rapist's/Insane people are basically frustrated people in life or people those who like to show their powers, such people get provoked seeing such things and they search for some victim on whom they can do such actvities, victim can be anyone, could be the couple whom they see carrying such activities in public. Its not 21st century/western culture, its more about family's safety. We realise things when someone close to us suffer else we seamlessly argue and call people as old and orthodox. Western culture teaches kids to make love, in school majority of guys and girls lose their virginity, do we indians like our daughter losing it in school? Atleast there'll be some fear outside the house for the youngsters.
