I think that's what this should be about, but I find so much of the talk about this subject when it comes to celebrities to be performative and false, especially when some of them (like Grande) have had controversies about race in the past. And I find much of the fan commentary to be performative and false, and at times more about people trying to show how "aware" they are than actually trying to help. For instance, sometimes I watch Stranger Things, so when I was on Twitter a day or two ago I saw various tweets from people who were essentially berating the young cast for not saying or doing enough, calling the cast racist, or saying they support racists, etc. How does any of this help anyone? I just find it to be another example of fans who invest too much of their identity in celebrities and also in their own social media image, which tends to focus more on how other people see them rather than what they actually believe or practice. There are problems in the world which can't be helped by hashtagging BLM and making a solemn photo with a link to a petition. And that's about as far as much of the Twitter commentary - from celebrities or regular people - tends to go.
I'm glad Joe and Dianne finally said something, but even then it's not going to really be seen as enough, simply because they can't do enough. They can give some money, and I hope they actually are giving that money, but they are still just a Youtuber who got famous for pranks and a dancer on a television show. In an ideal world, I'd say they could turn their channels over to activism, and give a voice to the voiceless, but that probably won't happen. Until it does, we're mostly left with two people who have no real authority to talk about these difficult topics. We just saw last week when Dianne talked about a topic (her diet) which a number of her fans were triggered by and were upset enough to where she had to delete the video.
I am not saying entertainers should only entertain, but there's a fine line in not seeming phony and grandstanding on a topic like this, and a great deal of what I've seen from celebrities and from hashtag activism types on Twitter has come across that way to me.
They should have decided to give money earlier, and I wish they had, but otherwise I think they would be better off staying in their own lane and not making a subject they have no experience with into a vanity project.
