Columbus was not the only Westerner to "discover" the Americas.
What about Amerigos Vespucci, Leif Ericson etc...I think there's even a claim that the Chinese have a settlement or naval base somewhere in America before Columbus...hmmmm....
Maybe Columbus is overated......
Anyways, acknowledge ALL his deeds, good and bad: we learn and move on but not forget. Sounds like a good idea to me, best of both worlds (pun intended).
Manx, don't let it hurt your head, it's not really worth it.
