Only been about 20 years since the push against using slurs. It’s shocking now to watch movies from 2010 and earlier because it’s so prevalent. How far we’ve come as far as respecting other people really obscures how long it really has been.
Really was an honest mistake, I didn’t find out she had mixed up the slur and word for larva of order Diptera until I audited her teaching class. The other educator with me didn’t even react and told me she had been doing it for as long as she knew her. Not her students, not the parents or other teachers ever bothered to correct her. She loved teaching about the life cycle of flies but her fear of accidentally slipping a slur killed that passion.
I’m not apologizing for the pope nor bigots at large. Just saying that there are circumstances in which someone who appears to be one thing isn’t, and you should be suspicious of being told what someone else looks like if you can’t see for yourself.
