I didn't want to call BS on the poster. It's possible she found a couple of Native Americans who don't find the term "Redskin" offensive. It's also possible that a rare Italian-American professed to not find guinea, dago or wop offensive. Possible. Undoubtedly uncommon but possible.
By the time I was born in the 50s most Italian prejudice had diminished considerably or moved far enough underground in my neighborhood that it was barely noticeable. High profile post-war entertainers like Frank Sinatra, Dean Martin and Sophia Loren sure helped.
Not so for many of my Jewish, Black, Hispanic and LGBTQ friends, who still deal with this ignorance.
Truly, I see a disheartening amount of thinly veiled racism on this very forum.
