I am a freethinker, and bear no allegiance to any creed or philosophy.
We have heard the fancy stories of ALI and his GIN. his gin is COMMITTED and LOYAL to him. hence ALLE + GI (A)N + CE. sound like reliance. so, when will u rely on anyone, simply if he is loyal to u. :) allegiance sounds like a league. after joining the league he was pretty loyal to it!
