Freedom of speech, expression and information is the most fundamental human right.
Freedom of Speech reinforces all other human rights, allowing society to develop and progress. It is the first requirement to allow ongoing Human Progress once the health of Nature, Climate and Planet are assured.
The ability to express our opinion and speak freely is essential to bring about change in society. A free society depends on the free exchange of ideas. Nearly all ideas are capable of giving offence to someone. Many of the most important, profound ideas in human history, such as those of Galileo Galilei and Charles Darwin, caused great religious offence in their time (adapted from indexoncensorship).
