This is really interesting if you want to go into a 13 minutes dive....basically even Kamala says her name "wrong" so what is right has a bunch of socio-linguistic factors to navigate
I love that guy - his videos are always worth watching. He talks about trisyllabic shortening in a way that probably makes sense to most people.
You guys are probably right that Trump is being racist with his pronunciation, because when he's talking about Kamala Harris every word will be loaded with racism and sexism. And also bullies often do do that thing of intentionally mispronouncing someone's name even when it's not for racist reasons (for Trump, it'll be bullying
and racism).
It's just that, to me, it didn't stick out as obviously racist the same way adding and emphasising Obama's middle name is, and that's probably because I'm not American. I mean, I've known at least one Kamala who pronounced it Kəm-AH-la, but that was in England, and she was probably Anglicising it when speaking English, like Dr Lindsey up there talks about.
My GF and her siblings also say their Bangladeshi names in English ways even when talking to each other on the phone in English. She also says it the English way when speaking in Sylheti - don't know about her siblings. For her, that is the right way, and an English speaker insisting on saying it in a Bangladeshi way would be being the opposite of thoughtful. It seems that's actually similar to Kamala Harris, who doesn't pronounce it the way Tamil speakers do.
So, for other people who say Kəm-AH-la, I wouldn't jump to assuming racism. Especially Brits, for whom, as Dr Lindsey explains, saying it exactly the same way as Kamala Harris herself does - which is the politest thing to do - requires using a vowel we don't actually have in British English dialects, and not just that, using it in a way that isn't a feature of our dialects (unusually, this is true for all British dialects, not just one or two dominant English ones. If anyone doesn't believe me, watch the video and listen to the difference between the sounds).
We can get close, and we should try to, but it's unrealistic to expect us to get it "right."
