Do you think that Polish should stick to Polish?
Of course, you guys need stick to your kind, especially when you live abroad (freaking ridiculous). Why did you decide to live in another country if you don't care about having your host country's friends? If you love Poland so much then why not just stay in Poland?
Nothing's wrong with Poland and Poles but be real people, if you decide to leave Poland, stick to your decision and at least try to adjust to the new environment.
