I know what you're trying to say, but I don't think "importance" is relevant here. Part of it is raising awareness. We talk a lot less about race here in Canada mostly because (I think) racial discrimination and racial injustices are lesser problems here than in the US but that doesn't mean they aren't problems. Now and then we hear about companies (such as Nike) producing their shoes in sweat shots. It's not an unreasonable discussion to talk about how the league and its players, for example, should be mindful of how their gear are made.
At the end of they day, the radio station is interested in discussing topics that listeners are interested in. A calculated guess would be that many listeners do pay attention to what's going on in the United States. Even if they aren't, sometimes, you do have to discuss topics that are harder to discuss because nowadays, if there's a big event happening in the world, it's a bit tone death to go about your business as usual without spending some time talking about it.
