"you are totally wrong the synonyms or terms of ""Kshatriya"" and ""Andhra Kshatriya"" was and is used for only ""Rajus"" but not other castes of Andhra Pradesh acording to Anthropological Survey of India by Kumar Suresh Singh which can be seen above and also in his other books.Because ""Rajus"" are kshatriyas and also called as ""Rachavaru"" in telugu in Medeival Period.Thats why Krishna Rao used the word ""Rachavaru"" and also he is not an ordinary man,B.V.Krishna Rao belongs to Andhra Historical Research society.According to Kumar Suresh Singh they are Kshatriyas who migrated from north india but not locals which is also supported by other anthropologers as the truth  is Aryans initially entered into Indian  Sub-continent and stayed in north india & north-east and then their castes i.e. Brahmins,Kshatriyas & Vaishyas gradully migrated and settled to south india.
