It was outlawed, and later written into the constitution.

I never said the caste system was abolished or doesn't exist. And I never mentioned 'untouchables'. It seems those replying and refuting anything I say are in favor of the caste system and want to keep it, which is utterly horrible.

If you cannot discriminate against caste, the caste serves no purpose, because you're effectively saying people are equal. But writing anti descrimination laws into the constitution obviously doesn't help society move away from it, especially when its so engrained into elders, or people who live outside the big cities.
