Never said the guy was Polish, just that plenty of the elder religious folk I grew up around had that cross in their houses and that it likely had a religious meaning, before being co-opted by the far right, that may still be in use with some groups.

Also I'm in the UK and my Polish family here arrived in the 60's, so likely a different cultural group to many of the Polish Catholic's in the US who, from what I've gathered, emigrated much earlier.
