Mr.Sitush! Listen point by point: 
 1.You can't blame K.S.Singh & his sources are unreliable.Because no source can be treated more reliable than Central Government of Indian Organizations like Anthropological Survey of India and also State Government Sources.Because they can't employ Historians with poor knowledge in preparing articles.Historians with poor knowledge may be present wikipedia to edit and delete articles with their personal reasons.Great Historians are used by Governement of India and State to develop caste articles based on survey.You(Sitush) being an Indian treating Government of India's Department like AnSI as unreliable is an insult to our country and unconstitutional.Government sources are the most reliable for castes articles as Government provides different types of benefits to different castes for their development.Treating Government Sources as unreliable is mere foolishness and it is left to your ethics. 
 2.Second thing is thousands of changes can't happen in castes list or castes.As it is stupidity in thinking that new castes will be emerged in recent period after 1947 and particularly last 10 years.Castes and their varnas and also their occupations are prepared according to their ancestral history and profession from medieval period,they are organized into different classes i.e OC,BC,SC,ST etc according to AnSI in different states of India. 
 3.Then,finally K.S.Singh's reputation is questioned by you.How foolish it is ?.After all you don't have the eligibility or status to comment on a Great Historian like him.It is nothing but a type of character assasination.K.S.Singh had written many books like castes,languages and about cultures of different states and people of different states and many more.All are accepted by AnSi and also verified by Oxford University Press.AnSI don't accept false theories and this is also verified by Oxford University Press.Caste Groups can't try to do anything in favour of them.Because AnSI classifies real ritual varna of Hinduism i.e. Brahmin,Kshatriya & Vaishya Varnas.And Sanskritisation can't be done in AnSI because only castes which are of their own real varna are accepted  there.I am saying this because you are always using the term "Sanskritisation",it really means that a caste of  shudra varna tries to improve their status to the above three varnas.But it is not at all accepted by AnSI.K.S.Singh provided 8 castes of Kshatriya Varna which are real varna.You also commented on ALL INDIA KSHATRIYA FEDERATION that is a advocacy group.AIKF membership is given to groups not individuals.Also Castes which Government accepted as Kshatriya Varna are present in the Group i.e. Rajputs & Rajus etc.Also the 8 Communities explained by K.S.Singh are real Kshatriyas who have ruling ancestry and dvijas and also they contain gotras named after Saptarishis and also other great sages.The problem is there with you and you don't want people to get aware of the History of lineages,gotras etc of Rajus caste because you don't like them i.e. may be your personal reasons.So,you are wantonly doing this and using wikipedia as medium.I don't like to comment on you further beacause it is left to your ethics. 
 4.Finally,Remember people are not fools to accept everything what you say.Iam again repeating again,no person or caste's status can be increased or decreased because of false statements or theories if you think in such a way it is your foolishness. 
 Therefore,notice that if Government of India's sources like AnSI is not acceptable as reliable,then the problem is yours not any one else,but if wikipedia don't accept Indian Government's sources then the problem is with wikipedia that no one can help.  
                     At last i'm tired enough to say as a conclusion,only one thing i can say,please maintain the reputation of wikipedia.It is good if you provide true knowledge  in articles for readers,otherwise what remains is only disputes and bad reputation for fake articles.Please take care in editing different pages in wikipedia.Thank you...
