The official position of the Alt-Right is that we want to create a White ethnostate in an unspecified part of North America, but I really think that people like Richard Spencer are just arguing for that in order to make the Alt-Right look less threatening. I personally want to turn the entire country into a White ethnostate with maybe some exceptions for existing Indian reservations.
Almost every single city in this country was founded and developed by White people over hundreds of years, so there's no way in hell that I'm ever going to support surrendering these cities. They rightfully belong to us just like Japanese cities rightfully belong to the Japanese.
And we're not stopping with America. The Alt-Right is a global movement for White people. We want to turn every single White country on this planet into White ethnostates. From Canada to Europe to Australia/New Zealand, we want to preserve all of these countries for the White race and create a new White alliance like NATO in order to ensure our racial security and prosperity.
Another reason why I don't think that a return to racial segregation is extreme enough is because I don't want any kind of financial or government connections to non-Whites. Low-IQ "Hispanics" (Amerinds/Mestizos) and black people tend to have inferior standards of living all across the entire world (including within America). They're always going to be like human leeches sucking off of our success. I'm sick of transferring billions of dollars in White wealth to these evolutionary dead-ends every year, and I'm sick of them having a voice in how we should govern our societies.
I also don't think that racial segregation within a country is sustainable in the long term if you try to divide White countries up into ethnostates. Eventually people of color will flood into our zones again because we create the best societies and their own societies are backwards cesspits. Eventually some liberal cucks will come to power again and open the floodgates to the darkie hordes. Or the non-White ethnostates in America will allow in mass non-White immigration from the rest of the world and create a kind of unstoppable human zerg in order to overrun the White ethnostates within America. That's why we need geographical buffer zones with non-Whites and a new national constitution which revolves around preventing our country from getting swamped by non-Whites again.
As to mixed race families; I personally support making miscegenation illegal again.
And as to mixed race people; here's what I recently posted about this topic.
It would probably depend on how White they looked and acted, their IQs, what the races were of their parents (hapas are probably the least offensive, while mulattoes are probably the most offensive), and how supportive they were of Alt-Right ideology. The most extreme scenario is that they'd be humanely deported. We're not calling for anyone to be violently exterminated. The Alt-Right is a religion of peace.
