Actually, Football, Rugby, and Soccer all have a similar sporting ancestry. Check out a run-down of the naming of these sports to relieve at least some of your angst about the testoster-sport. (It's understandable to have residual angst, though.)
Football came first. Rugby was a subsidiary of football and 'American' football evolved from rugby. Fact. I prefer to call it Gridiron.
