DR- i meant ask a rav whether it matters, what to do in safek, and abt e”y vs your city. Those were all questions you posed also in your OP.
Veltz meshugener- well, sooo sorry to be a cause of embarassment to you. Glad you feel we should all know better than our rabbanim who to give tzedaka to first
Rav Avigdor Miller said to do like Ms Critique did actually. That when the non-jew comes collecting on the train, you should give a penny or a nickel and make a kiddish Hashem, but not to give more, for there are Jews who need the tzedaka as desperately.
