L'kovod Rabbi Shapiro Shlita,
Are Jew's allow to say Umen to the prayer/blessing of a non-Jew (who we can assume believes in some form of minut/coiferah)?
Also, can someone who is Sephardi say Umen to a Christian's berachah (mentioning G-d) even though our shita is that this are flat-out idol-worshippers?

If the non-Jew says "god (the Avodah Zara) bless you;"
is it permitted to say, "Thank you" or "Thank you for your good wishes,"
just to be polite?
Rav Elchonon Wasserman ZTL did not bring US currency into the bathroom because it says on it "In G-d we trust." He said that when the Christians say "G-d" they mean the creator of the universe. When Rav Moshe Feinstein ZTL heard this, he disagreed, and said that when they say "God" they mean Yoshka and when they say "L-rd" they mean Hashem.
Rav Tuvia Goldstein ZTL, who was the one who heard this from Rav Elchonon and told it over to Rav Moshe (and from whom I heard this as well), went and asked a local Orthodox Galach for his input on this. The Galach said that he doesn't really have anything in mind specifically when he says "G-d."
So don't worry about it. You can say "Thank you."
