He is so right!
Being offended for someone else's convictions and beliefs is childish. In Universities we are taught to learn the beliefs of others, in a multidisciplinary environment. That is education. A place where we study and talk about what others say. We use a scientific method to prove and disprove the validity and reason behind the affirmations postulated in all subjects and disciplines; from physics to religion, to philosophy and archeology, math and music, art and reason, politics and money, human rights and wars, sacredness of life and pragmatic utilitarianism, etcetera.
We talk, and we are not offended at the systems of believes of others: evolutionist vs creationists, and even those that believe evolutionary and creationist theory are united to form a whole picture.
Some believe the Earth is at the Center of the Universe acting as the black hole event, others believe that Newtonian laws govern the universe, regardless of the mass discrepancies at far away galaxies. Some believe in Dark Matter, others the Principle.
What you study and hear might not be what you believe, yet you study what others think: we learn, we communicate. We are not offended, but rather expectant to find reason and a unifying theory of all things. Others rather believe in chaos. We are all learning, communicating, freedom of speech and convictions!
We believe as according to reason and understating, some religiosum voluntatits et intelectum obseqium, others in a wind of doctrines and unproven hypotheses.
Each chooses what to believe after being exposed to ideas and encouraged to find reason, or not, in each thesis, given by each of the different disciplines.
The Truth shall set you free, the splendor of the Truth.
We are all in a path of discovery, filed with expectation.
Amen
