To my understanding, what is commonly known as a Kiddush Hashem, when a non Jew acknowledges something good a Jew did, (and that Jews are good, etc), is a form of Kiddush Hashem (not intended to be taken lightly). The highest form is when a Jew recognizes how great a Jew is. (As in someones saying something like “Mi K’amcha Yisrael”.)
