First of all your understanding is wrong. Vedas are not the works of Brahmins alone. Do you know that In Hindu mythology devas are not considered brahmins. They have many architects and finciars etc. How come? Secondly Valmiki was a SC if you go by todays categorization. Brahmins merely maintained these works. You may be ignorant but please do not publish false information and create more hatred. If you cant do good atleast do do any bad to the society as a responsible person. You seem to be a pure HATE MONGER.
