What do you mean--we ALL know Saint Nicholas was a Rusnak!

The situation isn't much different among the Orthodox Carpatho-Rusyns in the US. There isn't much popular devotion to the Carpatho-Rusyn saints.
With regard to the Máriapócs icon, I think there is some "guilt by association" at play, given that it wept subsequent to the Union, that the shrine is Greek Catholic, and that it is located in Hungary. However, there is no stigma attached to the icon in ACROD, and our late Metropolitan Nicholas was the first Orthodox hierarch to visit the icon. A copy of the icon is also enshrined in the church at Camp Nazareth.
