Discussion on links/sources provided 

I think I provided more than enough sources and links that show the Ramdasia's are Chamars. The sources are books written by british authors 80-100 years ago, research papers, Indian constitution and official government of India websites.

If anyone disagrees, please post here with valid (& reasonable) arguments with verifiable links. 
Please answer these questions:
1- Why would three books (see above for links) say that Sikh Chamars are known as Ramdasia?
2- Why would so many research articles (see above for links) write that Ramdasia are Sikh Chamar?
3- Why do all official Indian Government websites state that Chamar & Ramdasia are the same?
