Few things would gratify me as much as a rediscovered respect for things belonging to others. Not abusing the property of others (or that of the community) is one of the ways in which we respect others. It is an essential part of being considerate guests, no matter where we are: in an airplane, in a friend's home, in a movie theater, in a doctor's office, in a public library, or in a public square.
If you have never changed your mind about some fundamental tenet of your belief, if you have never questioned the basics, and if you have no wish to do so, then you are likely ignorant.
