Roosevelt is actually credited for...quite a bit. First, he was a pioneer in conservation, and is highly responsible for the preservation of the beautiful national parks we have today. Second, he was labeled the trust-buster, and was one of the most effective presidents in cutting down on unethical big business practices. The whole thing about the monument being built on native land is really awful, unfortunately at the time of construction the disregard for natives and native tradition was really high (the Dawes Act, for example), but regardless of that, IF one were to make a monument like that, I think it's a bit silly to say it shouldn't include TDR....
