Over 2,000 schools have changed their logo, according to the article Mind Your Own Mascot By:Gordon, Devin. Also that Mr. Cooper a full blooded American Indian said his daughter became so offended, her eyes filled with tears and she asked if they could leave. So that tells me something that people can get really offended by these mascots, so I think they should ban them for causing all these bad things.
I think they should ban mascots because even defenders believe that certain Native Americans names, like pro footballs Washington Redskins, are offensive akin to referring to African Americans as “colored”. For example, the name "Redskins" suggests that all Native Americans had red skin, which isn't the case.
