The old-world antisemitism in a Christmas pageant near you

2. Minor quibble: while the Ukrainian Greek Catholic Church is in communion with the RCC,

...meaning it recognizes the Pope as the head of the Church, it is autonomous and follows its own Eastern Rite traditions.
Still, this cultural practice (I had no idea this was a thing) is completely shameful and you have to wonder about what is being taught or not taught in the homes of the parishioners. I'm certain that Pope Leo would personally be disgusted. In my experience, the RCC is not a hive mind inasmuch as there are both very liberal minded parishes with people trending to the righteous and hopelessly retrograde ones.
