What is the extent of the freedom of speech or expression?

I believe that your rights end when they infringe on mine.

Well,though everyone is free to speak his or her mind, there should be a limit to everything.Offlate,we have seen a lot of people expressing their personal views through the medium they work at which is hurting people maybe a single or a whole religion.I think such kind of practices should be stopped immediately.We must remember one thing that this Earth is for all the people out here and just for expressing your own thoughts you cannot hurt others who does not really agree with you.Speaking your mind definitely is a good practice but the correct time and place is also very much required.Then only it will have its true value.

any gesture that offends someone else doesnt come under freedom of expression but sadly some people dont think so and they define freedom of expression as they are free to do whatever they want and whatever the will, no matter how much their actions can hurt someone else's feeling.

Freedom is to be enjoyed until it does not harm the freedom of others :)
