The reason for this is found to be PETA. The Tamil people are seriously against PETA now and there is a severe heat on the organisation now. Already many famous celebrities and film personalities who have been the brand ambassadors of PETA have withdrawn their support now. It looks like the above mentioned actors are still having an association with PETA. Nadigar Sangam is looking at the aspect to send notices to them but it is still in suspense. More details about this will be out next.
