The immigration topic is so complex it’s hard to speak about without being specific. First of all – in my personal opinion – it’s not normal for masses of foreigners to live in one country and not assimilate. If you look back at history, it has never resulted well
for such countries. There will be always differences in upbringing, faith, tradition etc. Look at your country – what comes to your mind when you think about something that keeps you all together as a nation? Or about what brought you together? And what is causing a crack in the society?
I was an immigrant once and trust me, it was a huge eye opener.
