Well it doesn't affect you in anyway so why should you care what people in Poland believe? If they want to be "backward" thats their choice.
Yes it does, my whole family lives there and I spend at least 4 weeks per year there. I have to deal with all kind of crap for just wanting to see my family. Not to mention them speaking about it.\
I also have to deal with ridiculous opinions of my mother because of the stupid upbringing she had there.
