‘The freedom of a person as an individual and as an artist is, without a doubt, a high value that costs a lot. A healthy society understands, realizes the necessity and implements the “rules of free play”. At the same time, changes aimed at liberalizing society must be implemented carefully and gradually. Reforms have never been and will never be quick and easy. This is a complex and long-term process that requires us to be persistent and patient.’
