Why don't you look in the mirror?
Hmm - I pay taxes, use local facilities, use Polish products (in fact - I usually fill my car up at Orlen and not BP), don't get into trouble with the police (except that one time when I was caught speeding), employ some people, volunteer here and do my best to make this a more pleasant place to live. Okay, so I did spoil my ballot in the 2nd round of the Poznan mayoral election - and I am rather merciless about enforcing contracts and threatening legal action towards people who don't pay invoices - but hey, you'll forgive me, right?
Heck, I even spend money in the Polish mountains and not the Czech/Slovak/Ukrainian ones.
And what do
you do for Poland?
Could it be that it's not the enemy within that we have to worry about, but rather external enemies of Poland who are pretending to be friends?
