[quote=@Kratesis] How much of the planet should they share in order to be a moral ethnostate, in your view? 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? [/quote] Yes this actually happens constantly, because race and to a larger extent ethnicity is arbitrary, 'ethno-states' are barely ever realised. America is a perfect example, they still cant settle on the lines on what a white person is. The Irish, Italians, Catholics, Swedes, and a bunch of other groups youd consider white were not always included in that category making an 'ethno-state' pretty damn impossible by any working standard. And then even today there is split opinion over the whiteness of white hispanics, jews, and various arab and medeterrianian groups who may or may not look pretty caucasian. But the U.S. is complicated right? Lets have a more 'homogenus' example, maybe somehwere like china, or india. They seem like natural ethnostates right? Well China has around 50 different ethnicities, india has close to a couple hundred, which they can group and recognise but to the westerners eye they probably seem like on race per country. If you want to go by any working definition of ethnicity, there are very very few ethnostates in the world today, and even places like japan cant qualify when they are encouraging imigration to support their low workforce and stunted birth rates. An ethnostate doesnt ask non native people to come over and live in their country. As racist as the UK may have been in the 40s if it was an ethnostate it wouldnt have asked carribeans to come over during the 50s to repopulate the workforce after WW2. I'm not sure what your definition of 'implode' is, but ethnostates are so difficult to put together I doubt any of them have even gotten that far.
