If you elevate the taking of offence to the ultimate guiding principle, people will begin to operate out of fear of censure. That fear can impede creativity, especially in those who lack cultural power (which Cleese obviously does not).
It also makes it difficult to test your ideas in opposition to others’, something a university debating society should probably adopt as a priority.
