it is not "greekand/orturk" unless you are willing to give subjugation credence. bicommunal has nothing to do with this ethnic divide as such, rather it is a means to define the significance of State compared to Nation. as a member of a Nation you identify yourself a Person, yet as an Individual within the State all citizens carry none of these distinctions.
this is the single identity and constituencies X and T are dealing with. and the extremists will confound you by playing on your fears. to be bicommunal it is not possible to have two governing bodies, there must be many or one. one failed because the Communal Chamber was ignored, National Assemblies (a second level of governance) are an advancement toward reforming the Constitution of this Unitary State.
