How can you not see it as factual when it is a fact. The majority of people in Poland wish to stay in the EU — even if they don’t like the EU, they hate Ciocia Merkel’s ideas etc. The reason is similar to why Texas stays in the USA even during the Obama years.
I’m sure the Polish people have their MSM as the USA has its MSM. There is so much dust being kicked up and the Poles won their independence from the Iron block only relatively recently in the historical timeline. They are just getting started in what is a new experience for them. I am not particularly concerned about how they may or may not indicate a flaw in my reasoning. I am at a slight disadvantage because I have not visited all countries in Europe and Poland is one country that I have missed so far so I have no firsthand observation and discussion with natives in their native land. Otherwise I consider them an outlier due to the youth of their relatively new government and relatively newly won independence. Perhaps they need more time to figure things out. Perhaps they will always enjoy being an enigma. Who knows.
