I was born in, and currently live in Poland. It truly blows my mind that any Polish person could side with a foreign political party that openly sides with moscow over Ukraine and even Poland. Political alignment is truly the strongest drug for many people.
Also, while I think that barring a fringe part of society, everyone would agree, the fun part is, how do you get to people to agree who's pro-Russian or not ;) Of course, this is for local parties, but go to /r/Poland and /r/Polska and ask them, what parties are pro-Russian. Then to Wykop, both Mikroblog and frontpage, and see the reactions.
Anecdotally, my uncle just dropped by to thank me for the Easter flowers I had left at their place. He is pretty conservative, had always railed against this pope, and just called him a really good man. So at least today, religion and forgiveness won his heart.
While I support Ukraine and would like to see a stronger, more unified front from the collective West, making this the only question that matters in Polish politics seems wrong. My 2c.
