Chandigarh, Nov 15 (ANI): Even as the nation is trying to come to terms with controversial and abusive remarks by politicians during public rallies one after the other, the political parties are passing the buck to their opposition parties, eluding any kind of responsibility. BJP leader Anurag Thakur on Friday said that politicians should think twice before using any kind of bad language. Talking to mediapersons in Chandigarh, he also said that leaders should talk about policies and ideologies instead of pointing fingers on each other.
