BJP had assumed themselves the role of moral police to the nation and poking their noses into everything , which in their opinion, went against the moral fibre of this great ancient land..And three BJP Ministers losing their ministerial berth for an act, which is punishable under the Indian IT Act.
This can happen to any legislator or Minister, irrespective of Party affiliations. So the TN Govt may have thought it wise to make a pre emptive move. No amount of damage control is going to help in such a shameful episode. Hence the move of the TN govt is a wise decision. Other states, and even the Parliament may adopt similar decision, as the legislators and Ministers in States outside Karnataka, are in no way better than their counter parts in the state of Karnataka.
