[quote=@POOHEAD189] Well I guess it would be bad if they didn't share any of the whole planet. [/quote] How much of the planet should they share in order to be a moral ethnostate, in your view? [quote=@catchamber] Get two racists in a room together, and you'll get 3 opinions about where the lines between any two given ethnicities begin and end. The very concepts of race and ethnicity are outdated, and it seems they provide many more cons than pros. I imagine the colony would implode over time, due to shifting or vague definitions. [/quote] Can you name an ethnostate that has imploded over shifting or vague definitions of ethnicity? I'm sure this has happened; human history is replete with failed states but do ethnostates implode over shifting and vague definitions of ethnicity with greater frequency than multiethnic states implode over violence between separate ethnic groups? However your reply implies a rather large degree of confidence that this will occur. Have ethnostates in the past failed due to shifting and vague definitions of ethnicity that we can say with great confidence that a state must be ethnically heterogeneous in order to be stable? Furthermore if this hypothesis is correct what happens if all feelings of racial prejudice and animus between groups in a ethnically heterogeneous state fade away and they intermarry until all ethnic differences are extinguished and they become ethnically homogeneous once again? Does the state become unstable until they can import members of a different ethnic group into their state?
