Of course you can do whatever you want, if it is permissible by the laws of the land. If a girl and a guy want to do sex before marriage with their consent, then who are you or me to stop them. Of course, I would not have done it as I consider it immoral, but certainly I am no one to preach consequences of alcohol, Pre-marital sex etc to other people. A society becomes progressive if it uphelds the values without being forced to do so. Try to crack IAS / IPS, try to enter politics, get into the system and then change it. But you will not achieve anything by mobbing and moral policing simple because you DO NOT have the authority.
