Well I would also agree with your point Mohan Sir but this cannot be called terrorism I suppose . It definitely cannot be called terrorism, because terrorism means if someone uses illegal source of violence to fulfill their political views. People who criticize others should be considered as real devils. It is because they always carry a negative attitude with them that, what they believe and what they say is correct to all extent. That is the reason they criticize others. Such people can never grow in life. If we meet such people inspite of asking anything, we should rather move away from them with a thought, that Yes we will not get any solution to our problem from them. Rather the problem will be extended deeply. It is on us how we treat such people as such type of people are not meant for seeking any sort of advise or opinion.
A positive attitude will lead to positive results.
