To start the discussion, you can propose an example that is easy to relativize and later invite students to come up with their own examples, e.g.:
Students might come up with rules that refer to biology (e.g. you have to breath in order to live) and therefore are not really social rules. In some cases, you might reach a disagreement between the students, e.g. prohibition of torture: some will claim that tortures should be prohibited, as they are against human dignity, some will justify torture, e.g. when the tortured person has information crucial to save other people (e.g. has set a bomb and does not reveal the place where it is located).

By discussing different examples and different ways of explanation whether they are universal or not, you can show the students that:
