It would be a stretch to call a mascot a "hate crime." First, it usually isn't a crime. Second, most people don't hate Indians overtly. They're usually just stupid and ignorant, as racists tend to be.
Of course, the name "Redskins" violates the US Trademark Office's ban against offensive names. In that sense, it's a crime or at least a legal violation. A judge who understood language and the law would invalidate the trademark on that basis.
But if you want to discuss it, okay. Respected Native elders generally don't ride around on scooters and exhort people to shout epithets against Indians. Epithets such as the ethnic slur "Redskins." You are aware that most Indians consider this word an insult, aren't you?
Chief Zee doesn't discriminate?!
As for his intent, apparently you're unaware of the research proving that many people are racist on a subconscious or unconscious level. They don't realize they're acting in racist ways but they do it anyway.
More to the point, who cares? I'm judging Zee's stereotypical actions by their effect, not their intent. In case you're ignorant of the voluminous evidence against mascots, read Team Names and Mascots and The Harm of Native Stereotyping: Facts and Evidence. Educate yourself so I don't have to.
Below: Pop quiz for "T.": Match the Washington Redskins' mascot (below) to the race or ethnic group he's stereotyping.
a) Indians (e.g., Sherman Alexie or Adam Beach)
e) All of the above.
Unless your answer is e), Chief Zee is a discriminatory, racist stereotype of Indians only. Duhhh.
