`Hi   a group of wikipedians legislating their own wiki rules here, they got their own personal interest.  I have provided many books here (WP:RS) which clearly show the difference of these two castes but these admins only trust those books which come inline with their views. Thats why i said ``personal interest``. Wikipedians should think neutrally but here i have seen wikipedians biased  and stubborn on their views even though it is strange and illogical. They decide which book is reliable and which is not reliable. If you look other caste related wiki page talk pages you can see same admins interfering and saying their opinion on them, even though they know nothing about the subject.  I saw one recent reply from Yogesh in ANI page to your comment . It is silly, his reply is completely out of context.  This is how some admins operate here.  .     `
