What about the lost tribe?

What about the lost tribe? My rhetorical answer/question to a poorly questioned question.

Okay, what you mean is, was there a lost tribe of Israel (from Biblical story), and what happened to it? Some say the Ethiopians are the lost tribe, other say the Navajo, still other say it was the Tibetans, or the Persians. Does it really matter? The story might really be about how any one group eventually has sects that splinter away and are considered lost. Low is the person who denigrates other sects, let them be. Have tolerance of other religions and other denominations, because they are not out to get you.
