UnhingedTaboo you will only find those in the illiterate people living in rural area and towards the people from Nigeria.
The biggest problem here is the caste system not racism
I'd disagree somewhat. It's not directed at just some 'Africans', nor is it limited to illiterate people living in rural areas. It is really prevalent among even the university students that never confronted the things they'd been taught by the family and the society over decades. And it's not hard to test. Just keep the idea in your mind next time you go about your life, you'll find out. It's not always the biggest and most overt things that hurt us. And because people don't think it that big of a problem makes the problem this problematic. You can never confront a problem if people don't see it as a problem.
