You are only living in TN for 15 years. But I am a telugu guy born here. I also have lived in Hyderabad for several years. Also lot of AP students studied with me for around 6 years in university. I can easily say that, caste based racism is rocketing in AP. In tamil nadu, its mostly the brahmins (not all brahmins, but only racist brahmins) who show lot of neglegence to others based on caste. Apart from that, caste exists in TN only at the level of getting govt. jobs and scholarships. Have you even seen own co-brothers butchering themselves? It happens in the AP and called as fractionalism. You first try to speak truth.
