From the parameters of the question a large number of self-identified Jews in America don’t count. Maybe most. What counts as “actively practicing”? If I am an atheist who goes to Yom Kippur services out of an appreciation of the tradition, am I practicing? Not by any Orthodox standard. But by standards of American Jewishness fer sure.
I don’t know about the question being offensive, but to many Jews it is at least ignorant and not with any meaning.
