I'm a person living in a muslim country. There are lots of problems/discussions between religious and non-religious people about the limits of freedom. For example, some religious people say that they feel offended when someone nearby drinks a alcoholic drink. On the other hand the non-religious people say that it is their freedom to drink alcoholic drinks. There are many other cases of this type, that is, one say that they get offended (generally the religious ones) and the other say that it is their freedom to do such and such. My question is how should we think about such issues? Are there general principles about limits of freedom that we can use to solve such cases? Also, can you suggest introductory reading material on this issue?
