I definitely disagree on this point. Destroying the nation and undermining any ethnic ties within a community is the prerequisite to implementing communism. Communism requires sameness, anchorlessness, destruction of the (extended and nuclear) family, and a denial of the right to own and control access to property. Open borders are a clear means to these ends. I am aware that there are right-wing anarchists, but I consider that to be an oxymoron.
