The House saw a walkout by Congress, Trinamool Congress and RJD over the issue.
The SAD-BJP government of Punjab came under attack from Jyotiraditya Scindia of Congress who cited crime figures to allege that a case of atrocity against Dalits was taking place in Punjab every 18 minutes and three Dalit women were raped every day.
He then referred to the chopping of limbs of two Dalit youths in Punjab recently and another incident in which a woman was allegedly run over by a bus whose owner, he alleged, was close to the ruling Badal family in the state.
Reacting strongly to his, Minister Harsimrat Kaur Badal, leader of SAD and daughter-in-law of Chief Minister Parkash Singh Badal, accused Congress of trying to destabilise the state government and stall development by raking up all kinds of issues in Parliament.
She alleged that Congress leaders were supporting demand for Khalistan.
Regarding the hand-chopping incident, Kaur accused Congress of politicising the issue of a "gang war". She said in this "gang war", limbs of a Jat Sikh were also chopped off but the opposition party was not talking about it as Jat Sikhs were not its "vote bank".
Hitting back at Congress, she cited figures of "atrocities" against Dalits when Congress was in power.
Earlier, while many BJP members protested against the decision to allow Scindia to raise the issue in the Zero Hour after his party's hour-long protests in the Well, Speaker Sumitra Mahajan said 300 members were suffering from "dictatorship of a few".
The Speaker, who had earlier cautioned members against raising state issues, disallowed him and expunged his comments against the family.
When Kaur, wanted to reply, the Speaker told her that it would put the reference to her family on record.
Naidu accused Congress of "misusing the forum of
Parliament to defame and destabilise a democratically-elected government" and questioned its practice of first protesting in the House and then staging a walkout after raising an issue.
"It cannot be a one-way traffic. You first abuse, then walk out," he said, adding that Congress members were "abusing" the prime minister.
To Congress demands for dismissing government in Punjab over the hand-chopping incident, Naidu wondered whether governments in Karnataka and UP should also be dismissed over the murder of M M Kalburgi and Dadri lynching, respectively.
She said she would meet with leaders of all parties to find a way out.
Amid the uproar, Congress leader Mallikarjun Kharge too wanted to speak but was disallowed.
