Hi   a group of wikipedians legislating their own wiki rules here they got their own personal interest  I have provided many books here WPRS 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
