He was responding to a question about chief minister Jayalalithaa's statement in the state assembly on Wednesday.
In a suo motu statement in the assembly, Jayalalithaa came down heavily on the July 11 incident in which sitting Madras high court judge D Hariparanthaman was barred from entering TNCA Club for wearing a dhoti.
Calling the denial of entry "an act of insult to Tamil civilisation and culture", she warned such organisations of stringent action, including cancellation of their licences.
She also said the government would enact a new law to curb such practices.
The incident has triggered a controversy with almost all political parties condemning it.
