Very low. Jews distrust religious bigotry of any kind, as bigotry against any religion can easily be turned against Jews.
...It is remarkable that when the Jews really controlled Hollywood around 1940 they made a seemingly-unlikely stock hero: the Catholic priest. But Catholics were not yet completely accepted in American life, and there was much garbage out about Catholicism.
Jews might have also wanted to isolate Father Coughlin.
He's not for Palestine, Hamas, etc. I don't understand why some Jews despise him. I can see Riverdale, Bronx making Bronx a little bit competitive.
