to celebrate or not to celebrate the columbus' day

It is true that Columbus is viewed as a national hero for his discovery of the new world in which now tens of million people live on. However, a day in name of columbus is not necessarily needed because America is a diverse and multi-cultural country which includes people from differnet ethnics who might hold different point of views in the same issue. It is not fair for those people who dislike Columbus' acts to celebrate him as a figure of bravery and spirit of american culture. American people definitely need a day to celebrate the courage of exploring but it is no need to set it in name of Columbus.
