I think it was left-wing Sicilians or Italians. I don’t really know the immigrant makeup of Sicily. Walked into my my husband’s elderly communist uncle’s bathroom and there was a pix of him dressed as a 1930s fascist.
I asked because Sicily is right in the middle of the trade routes and immigration routes, meaning that a lot of muslims pass by and maybe land there. So it could be imported, but it sounds like there might be a healthy dose of home grown as well.
