I'm more in favour of integration of newcomers
Can't seem to watch the vid in Japan. Will try Youtube when I'm through with Game of Thrones Season 4 (always behind, me).
I can't imagine going somewhere and not trying to integrate. It makes life so much better and more interesting.
Of course you never truly do integrate; you retain a supplementary layer to your identity that enriches you as you further enrich yourself by adapting to new people and new ways.
Integration should perhaps be seen as a process of personal enrichment that in turn enriches broader society,. Break down the fear of loss of 'identity'.
