Nobody says kissing is bad ( as depicted in the article). But, kissing in public may be embarassment for all and since it is a public place where all sorts of people come, it is better to atleast control the urge in a few places and open up when you are private.
Nobody says boys and girls speaking is bad( as depicted in the article). But, putting say topless or other revealing shirts is that too not in any place. Only in education camups where there needs to be a minimum decency dress code. Dress codes are there in IT firms. Dress codes are there in foreign countries too and even in places where there are none, quotes had been there to put some pleasant and professional dress as much as possible.
I think the author is A self styled leftist like one famous indian newspaper editor who thinks that they are liberating the world with their new modern non-superstitious ideas.
