The protesters, led by PDP leader Yasir Reshi, held the rally at Press Enclave here and shouted slogans against Lone, who belongs to the ruling National Conference.
Lone had a heated exchange with PDP legislators at a meeting of the District Development Board Bandipora yesterday, where the leaders of both the parties used "unparliamentary" language against each other.
The protesters claimed that the people of the area "do not want to keep any links with him."
"We cannot tolerate anything against a respectable person like (PDP MLC) Naeem Akhtar," they said.
Criticising Chief Minister Omar Abdullah, Reshi said "is this (abusive language) what the government wants to preach to the students?"
The government should have sacked Lone as a Speaker when he used "abusive language" against PDP MLA Iftikhar Hussain Ansari in the Assembly, Reshi alleged while referring to an incident two years ago.
The protesters tried to march towards Lal Chowk, but police stopped them and took dozens of them, including Reshi, into preventive custody.
