Remind me, how does a country practice antisemitism without a Jewish population? Jewish culture survived in Odessa too, but I'd hardly credit the gentile Ukrainians with such an accomplishment.
Most populous regions in Europe for us gypsies is Spain and Romania, do we have to be masochists for staying in spite of fascism? No, we just need to be tough.
I could just as easily assume that your premise is based on how Jews are cowards who go from country to country looking for a handout, and then the Poles decided to be charitable. But I don't assume that. I don't assume anything. Your assessment is wrong, but it can be wrong on a myriad of bases, not just the ones that make me look favorable by comparison.
