In democracy, political expression of social divisions is normal and can be healthy. In case of India and Belgium, it has been observed that social diversities can be accommodated in a very positive manner. But a positive attitude towards diversity and a willingness to accommodate it do not come about easily.
People who feel marginalised, deprived and discriminated against have to fight against injustices. Such a fight often takes the democratic path, voicing their demands in a peaceful and constitutional manner and seeking a fair position through elections. Sometimes social differences can take the form of unacceptable level of social inequality and injustice. The struggle against such inequalities sometimes takes the path of violence and defiance of state power.
However, history shows that democracy is the best way to fight for recognition and also to accommodate diversity.
