There's the media posturing and then there's reality. A lot of people in Poland have not had any contact with other cultures and make inappropriate jokes about that, those who traveled a bit are totally ok with it, the last 20 years introduced a lot more multiculturalism but there's still ways to go. The leading right-wing political party is a data driven monsters - they will build their policy on whatever gets them seats in parliament and local elections. One the most successful right wing policies in Poland right now is 500+ - a form of Universal Basic Income for every family with children. This clearly a very socialist idea, but introduced by a 'conservative' party. My point is the conservative party, like most of Poles are very pragmatic and generally will do what works rather than being too principled. If you understand that, you'll gel well with the society in Poland.
