Thinking it still doesn't make it so, though, else we'd all be racist over even the slightest little imagining of offense, with a hefty dose of mental gymnastics, that seems to crop up these days...
I agree that thinking something is racist doesn't make it racist but it's not hard to see how people make the link. That requires literally no mental gymnastics and if anything just a mental stroll across a road.
Try and see it from someone elses point of view as well as your own.
When you were growing up, I am going to presume for sake of argument that you're not black, did you frequently have people making monkey noises at you or suggesting you're the missing link between Ape and Man? If you haven't experienced that then I can completely see why your mind doesn't go there initially. That doesn't make you wrong or ignorant, it just shows you didn't have those experiences growing up so your mind doesn't go there.
Now, if like me you did grow up and that did happen to you several times, can't you see how someone like myself
could view it as racist or at least racially insensitive?
This, to my knowledge, didn't happen with either of William and Kate's children. So when it has happened to Harry and Megan's first child who also happens to be the first mixed race royal baby it's not that difficult, for people who have experienced certain things, to make the connection.
Maybe he did mean it purely in the way he intended and people took it the wrong way. It wont be the first and last time this has happened.
I don't know how much you follow boxing, or a few other sports, but Matchroom founder Barry Hearn came under some heat recently because he said in his years Promoters acted like Slave Owners with the way they treated boxers. Anyone with 2 brain cells will know exactly what he meant but because he had 2 black guys either side of him people twisted it to mean something much worse.
People are very quick to twist narratives today, especially without context, so anyone in a position where thousand will see what they say need to be careful. I don't think he deserved to get fired unless he had a track history of such actions but I do think he was a bit silly to not see the racial connotations, especially someone of his age who probably lived through more of it than the ones getting offended.
