As Polish I can assure you that courts wouldn't punish them also in the case of writing anti-christian slogans on a church, or catholic cementary. Somehow Polish courts are like this. They are just not harsh. I'm not sure how could I put it differently. I.e. a friend caused car accident in which another person had to be hospitalized and their kidney taken out. The court fined him with 1 month salary. No prison time, not much prosecution happened. 1 month salary fine, he was free to go. This being said Poland is deeply antisemitic country. I'm sad to say it, but there is no way to deny it. But then again Poles are quite hateful in general. They don't like Germans, Russians, Czechs, whatever. And most interestingly they hate each other too. Poles hate Poles. When two Poles meet it does't take much time before they start complaining about Poland, they loathe the place. That's why we immigrate. I think that in New York Poles had this stereotype of being most hateful nation. I think that's true.
