According to the universal declaration of human rights, article 9, everyone has the right to freedom of thought, conscience and religion. The rise of extremism which advocates extreme measures or views on different subjects, such as politics or religion for an ideology, is a threat to this human right.
Extreme movements often tend to exclude diverse opinions and instead accept like -minded parts. The ways of the extremists can be fatal and threatening to those that are not included in the same movement, making the extremism a great threat to the human rights.
“Our ability to reach unity in diversity will be the beauty and the test of our civilisation.”
― Mahatma Gandhi
