OBC reservation is not based on caste only. Patel belonging to gujrat are never given any kind of reservation. However, those living in UP are provided such kind of facility. I am not saying that all the reservation policy is totally correct. However to survive in this nation, you have to move with certain dark aspects in order to spread more light.
I couldn't understand about the mentionality of those who are opposing the reservation.
Like you i am also against of any kind of reservation. however, you will have to reform whole society from the ill effect of caste.
Remove the caste from the entire society in all aspect including marriage. We won't be needing any kind of reservation.
