Human rights are also called fundamental rights. These are rights stipulate, for instance, that everyone has freedom of expression. That everyone may freely profess their religion or belief. That everyone has the right to privacy, the right to keep personal information private.
People are not equal, but they are of equal value. They have equal rights and are equal before the law. These human rights are an important principle of any democratic society.
Why do these rights matter? Imagine that these rights did not apply to everyone. That in your country, a certain group of people would not be allowed to express themselves freely or to practise their religion freely. That a group of people, not suspected of any crime, would still be monitored by the government.
All this would make for a very unpleasant society. One in which one or more groups of people would repeatedly be slighted and discriminated against. An unliveable society. Would you want to live there?
Human rights are worth defending. And everyone can make a contribution!
