sometimes the last name gives it away pretty easily. An evangelical revival probably broke out so they have to reign in the Christians.
Sometimes, but even that isn't tried and true.
Also people marry Jews and are assumed to convert, which they don't always do.
Sometimes a Jewess will marry someone with an Irish name and who would know that she was Jewish (Howard Dean and wife) unless s/he "announced" it?
My question still isn't answered.
An evangelical meeting? Lol, just A LTTLE prejudice on your part peeking out? Why assume they are, en masse, bigots?
