In an address marking the country's 40 years of independence, Mogae said he was worried about the growing trend by some citizen groups, who claimed that their languages and cultures were being marginalised, to organise themselves into ethnic cultural groups.
"While it is perfectly legitimate for tribes to promote their individual cultures, we should avoid setting up exclusive organisations whose membership is drawn from one tribe ... Our goal of nation-building needs to prevail over narrow tribal sentiment", Mogae said.
Jumanda Gakelebone, a spokesman for First People of the Kalahari, a local pressure group, said the marginalised ethnic communities had formed groups to stop their assimilation into the eight Tswana tribes recognised by the constitution.
The Batswana form the majority of Botswana's population, with the Kalanga, Basarwa, and Kgalagadi constituting four percent, mainly in northern and central Botswana, but the languages of the San, the Kgalagadi and the Kalanga are not used on national radio or taught at any level in local schools.
Reteng, a coalition of ethnic cultural groups, said it was "regrettable" that the government continued to view the activities of marginalised ethnic groups with suspicion. The formation of cultural groups should be acceptable in a democracy, it added.
"The cultural societies are open to anyone who wants to join, but they will always attract those people who belong to that particular culture and have a passion to preserve its language and traditions", Reteng said in a statement in response to Mogae's remarks.
"The government should view the formation of such cultural groups as a sign that something is terribly wrong with our national language and culture system. The minorities are simply refusing to accept the notion of cultural inferiority. We are refusing to be assimilated into language and culture systems that are not ours. We all cherish a united and culturally diversified Botswana, but the government should stop perpetuating colonialist mindsets in which some tribes are considered inferior to others", Gakelebone told IRIN.
Presidential spokesman Jeff Ramsay said the president's speech was not a directive against any ethnic groups, but a mere expression of concern over the proliferation of exclusive formations.
