Say what you will....I would have the same opinion of any other historical monument even if I personally find it offensive. You are the one with a one track mind/agenda. 
So I herby declare that all "white men" be removed from this country for all the atrocities they committed against my people because it is a painful part of our past. NOT !   (  A Native American standing up for history Lee Mayhan....What say you now ???????) See where all of this is going ? What is next after this....Start tearing down mosque, temples, churches because some religions have a "painful past". 
Where des it stop ?
