The Buddha always encouraged open discussion which included differing viewpoints. He encouraged the individual at the same time as teaching compassion for all men, and was very democratic in his style.
Buddhism is also relevant for the scientific and technological era in which we now live. Albert Einstein is quoted as saying "if there is any religion that would cope with modern scientific needs it would be Buddhism". The emphasis on the clarity of thought, of seeing and understanding, and of being aware of constant change are all fundamentals of a scientific approach.
Also, Buddhism offers a path, which provides guidelines for everyday living and for a caring approach to the environment. It shows us the way to live in harmony with others and the world we live in.
