As a kid, I loved the Washington Redskins and Indians. As an adult, my position has evolved.
I believe the National Congress of American Indians among other native groups has been advocating for this since at least 1968, but lets diminish their input.
Debate is good and healthy and helps move a society forward. Politics infuse all aspects of life and sports are no exception. As I've noted before, Jack Trice's presence on the field was inherently political in light of politicians of the day agitating to keep the races separate. I'm sure people at the time cried foul and advocated to keep him sidelined, because they didn't want all this political crap sullying the game.
Cat Stevens had a good rebuttal further down.
I will note that some other sports teams have nailed this tricky balance, while the Indians and Redskins are just beyond ridiculous at this point. Miami (Ohio) University added a great logo that honored the Miami tribe, in partnership with them. See it here:

Would you ask the NAACP what level of racism/stereotype is ok with a Sambo caricature or a "magical negro" trope then rail against them if they demonstrated an unwillingness to find a common ground in your "respect" of their culture?
Through American history, native groups have suffered from mass genocide and subjugation and still suffer some of the highest poverty rates in America. The Indians were not named because of "the Tribes in Ohio and them being strong." Much research has been done into the psychological harm that stereotypical behavior and tropes cause, especially in impressionable children. It also has socioeconomic impacts on adults.
Your "history" of the Fighting Irish nickname is also blatantly wrong. I believe four of the six originating priests of Notre Dame were Irish and the school was originally overwhelmingly Irish, thus the Irish school essentially named themselves. Also, just like any other team name of the era, they were the Fighting Irish, just like the Fighting Tigers, Fighting Cyclones, etc. It was a turn of phrase.
But it's good to know that you aren't offended by the logo of a mythical creature--the leprechaun. I'm sure the leprechaun people appreciate your support.
