Tamils won't eat cows/bulls few sects of people eat them. I hope that above post from such sects..........
Maintaining Jallikattu bulls are not an easy task first you need money ,lands, dedicated man/labours . If somebody selling such bulls means mainly due to financial crisis (sometimes aging problems) but definitely not for money.
All over India there are sects that will eat beef. I myself eat beef, although I do not belong to any sect that eats beef. But what Maravan posted above seemed to present a wrong information as if these people are representing TN entirely. Hence my argument. You are certainly right when you say people sell bulls only if they are facing a crisis.
