Granted, Presbyterian theology tends to a “replacement” theology and so has less of a philosophical reason to be friendly towards Jews. It’s far less of a problem with dispensationalism e.g. most Southern Baptists.
Your knowledge of that is surely greater than mine.
But there is no excuse for their ignorance of history and current events. It’s still bigotry on their part. As far as I am concerned anyway. I readily admit to being highly opinionated.
