I think people don’t notice the distinction of X or + if it looks anything like a swastika tilted or not, our antenna go up. I think Native Americans have a similar symbol, I vaguely remember that on a Fluther Q.
The thing is this is Chanukah paper, so it is in the context of the Jewish religion. It doesn’t matter that it is in a drug store.
If I enter a Buddhist temple I would probably be surprised to see what reminds me of a swastika and ask about it. Just like when I was in castle Neushwantstein and saw wallpaper with what I call stars if David, but they just call them 6 pointed stars. Or in the Rome I think the church is St. Ivo alla Sapienza that has a six pointed star in the ceiling that allows the sun to come through.
@kevbo Good point about the irony of the Greek Key.
