People should not discriminate against anyone based on their language, colour, sex or race. Anyone over the age of 18 has the right to vote. People have the right to their own nationalities. No one can own you. People have the right to equal access to public services in their countries.
People have the right to equal pay for equal services.
People should be able to join trade unions. I hope that you will read more about how we should respect each other because people who discriminate don't realize how much their victims hurt inside. In schools, students should do less teasing of other people and more helping and encouraging. Let's make this a better world.
