Malay right-wing group Pertubuhan Pribumi Perkasa today threatened that it would react to the actions of those who chose to question Malay supremacy.
President Datuk Ibrahim Ali said that for the sake of "the country, race and religion, I am willing to be detained under the Internal Security Act" should Malay rights be challenged.
The Malay nationalist politician warned non-Malays to behave, if not then Malays would repay in kind.
"If they are polite, we will be polite. But if they are not, neither will we. If they are kurang ajar (ill-mannered), we too can be kurang ajar," said the Pasir Mas MP to cheers from the thousand-strong crowd.
Ibrahim as president of Perkasa had last year also called on other races to adapt to the local culture of Malays as they have already been given many rights and freedoms in this country.
Today, he added that those who questioned the issue of the special position of Malays were not acting in the name of justice.
"The truth is that justice has not yet come to Bumiputeras who have spent centuries being oppressed by colonial masters," he said.
The former Umno leader said that in the past, Malays had been reasonable with the colonial masters but that they would not tolerate "our heads being stepped on."
"We will not tolerate Bumiputeras losing face or our honour. Especially Malays and Islam, do not ever try to play around with these," he threatened.
