It’s discrediting valid concerns against card-payments. It’s invalidating how great cash is.
It’s when the worst person you know makes a good point.
And things now are so Culture-Wars-y, nobody makes solid analyses any more, that when the far-right say cards are bad, everybody jumps to thinking cards are good.
I actually saw a sticker recently placed on a bus stop saying “save Poland, use cash” and I was very perplexed by it. I suspected it was some far-right/alt-right bs, but wasn’t sure.
