If the fact that i obey the law instead of commit a crime breaking immigration rules doesnt make me better,
Which Polish law would an immigrant who is sent to Poland by the EU be breaking? None, so you are no better than them.
That said, I very much doubt that the fact that a non-white immigrant is not breaking any Polish law will make any difference to xenophobic racist Poles; they will still want the non-white immigrant to get out of their country.
As you already know, i lived in a very poor city in Poland and i never faced any demonstration of racism.
Utter rubbish! You lived in a city which ranks as the 32nd richest area in Poland, there are far poorer parts of Poland. Also, that city is among the most tolerant in Poland, due in large part to the number of decades that foreign students were sent to it. Try visiting a place such as Radom and acting like a big-shot superior rich foreigner, you'll soon find how tolerant some of the locals there are of people they might consider to look like Roma and to be in need of a lesson.
