Greetings from fellow countryman
It's visible where you come from. All slavs have specific hard, strong accent, that indicates we're from Central or Eastern Europe. After a five minutes of chat everone will know you're from Poland, Czech Rep., Russia or Serbia. So you won't hide it.
In that case, try to demonstrate you're different than some stereotypical guy from Poland. I don't see reason we should feel less or more worthy than any other nation. Just show you're a cool guy regardless of place where you were born.
About Polish jokes, say, yes, I know them, but consider them stupid and know some far more funny. Or admit they are to some extent true but what's the matter? Every nation has its weaknesses that are ridiculed abroad.
Ahh, don't mention John Paul II. It won't bring you any higher value. For how long we can boast with one man? It becomes boring. Not mentioning the fact, few young people in the West (I assume you live in Western Europe now) believes in God and have respect to church representants.
P.S Miło kurwa spotkać na tak odległym forum kogoś z Polski
