Are you sure? Just because few idiots like Ang Kagi say it loud does not make it a general sentiment. Our caste system is nothing compared to the one in India. We are way way more liberal. If we can't change the caste system at a national level, let's change it at grass-root level. Change yourself, like Hurray said. Let your brother, sister, cousin, children marry someone from so called "lower caste". Correct your parents, relatives when they have a biased view towards other castes.
