Supporters of independence point to their belief that Quebec is a nation due to its unique history, shared major language and common heritage. Opponents of sovereignty generally believe it to be a dangerous idea due to the political, financial, personal and economic ties between Quebecers and other Canadians. Some see it as being unnecessary due to Canada's multicultural and bilingual national character, as well as the strong status of the French language and culture in Quebec. Opponents to Québécois nationalism point to the fact that Quebec is just as ethnically diverse as the rest of Canada and therefore is divisible by different ethnic and language groups, or point to the shared Francophone heritage of the ROC (Rest of Canada). Many federalists believe that Canada comprises many nations in the cultural and ethnic, non-political sense; and that Quebec can be divided into just as many nations as Ontario or British Columbia.
