If there wasnt a Christopher Colombus, many of us wouldnt be in America today. Thats a fact. America would be called something else and wouldnt be the power it is today nor would it be th innovator it is today. Christopher Colombus was extremely brave, intelligent, forward thinking, and took on a huge risk for the betterment of mankind. That should be celebrated.
I think part of the problem is some people dont have a national or ethnic hero to celebrate so they attempt to eliminate the accomplishments of others. Think about that.
