I've listened to Dotun Adebayo a few times, especially because I do like his music and sport talk. I generally like him as a presenter and he's really good at everything really. The only bug bare is a lot of the time he won't give his own opinion on more important topics.
I remember the black lives matter talk, where he had guest and people phone in, and he often held back about giving his opinion. He spoke of a couple racist incidents in London when he was younger, but apart from that nothing.
He doesn't seem like someone who anyone would dislike though, to be fair. I remember a caller calling in and she mentioned how she didn't like Nigeria when she went, and it was just a bit of a distasteful comment while speaking to Dotun, who is a Nigerian man. I'm pretty sure she was an older white woman, so maybe she didn't think how she came across.
It sounded a bit blunt and disrespectful. He didn't really call her out or start an argument over it, but instead just carried on with the subject at hand. As I say though, he's a good, knowledgeable presenter, and he'll cover all topics well.
