Why is that? I don't really see disputes on those pages although I haven't read most of them. Can you point me to a specific case?
I have yet to see *one* such page confirming to anything approaching wiki standards (I don't mind the Indian English of these pages, that's sort of cute)... of course almost all authors are members of the community in question. (While lower castes articles are usually copied out of some sociology book of fifty years ago, and are usually of stub length though there are surprising exceptions.)
It tends to get crassest when the group's status is at least somewhat ambiguous rather than universally accepted as high (of course, that really applies to the vast majority of modern "kshatriya"). Check the Meena page, for instance, for a hilarious example. That one actually seems to have had edit wars... usually nobody cares.
