It's a fine argument for people who grew up during a time when "colored people" was the less racist way of referring to POC.
Like, maybe this guy's great-grandfather, seeing as the NAACP was named in 1909.
But, to be a bit more charitable, his grandfather probably used the term (it peaked in usage in the 1960s), and maybe his father, if his father was one of those people who stubbornly resists change. But Rep Crane himself was born a decade after "colored" had gone from the least racist term to a decidedly mid-level racist term (after social shaming began to be applied to the more racist ones).
Ah, I see. I wasnt aware said org had over a 100 years of existence. Some comments here gave me the impression that this term was ok a short time ago but if we're talking about multiple decades then this sounds like a mayor fuck up.
