Gimme a break. This is one of the stupidest stories I have ever heard.
For one thing, most Latin Americans who come here, except for Indians from remotest Guatemala, are of European descent (Spanish, English, French and German) and thus would be considered “white.”
But this has nothing to do with ethnic groups. It’s simply an account of the foundation of national parks. Theodore Roosevelt, like him or not, was the founder of national parks, not only for the US but ultimately for Europe and the entire civilized (i.e., non-Muslim) world.
Yosemite, from what I have seen when I have been there, has an enormously diverse visitor base from virtually every country in the world. The only people who don’t travel there much, based on my purely anecdotal research, are US blacks, but that’s their problem. Maybe they should look beyond their skin color and become human beings.
Not to pick, but I get a couple of Canadian channels, and I heard a commercial within the past week or two bragging that some national park in Canada was the world's first. I had it on in background, so I can't give the specifics.
Any way, it only pricked my interest because it conflicted with what I had understood about TR and national parks.
Since there really were some Buffalo Soldiers at Yosemite, spending a couple of minutes on their role in a two-hour tour would make sense, but there are an awful lot of other topics at Yosemite deserving of attention. They shouldn't overlook Gifford Pinchot, one of the patron saints of the environmentalist movement, and his support for the Hetch Hetchy dam--good for San Francisco, bad for people who can't see what a beautiful place it was before the dam.
Pinchot created the template for the left-wing character-assassination hit job with his attacks on Sec. of the Interior Richard Ballinger. When Ballinger resigned, President Taft said he had been "the object of one of the most unscrupulous conspiracies for the defamation of character that history can show."
Pinchot is also the one who had the bright idea of reintroducing deer into areas of the eastern US where they weren't found--soon to become a major nuisance because of the lack of natural predators to keep the numbers down.
