As more comes out about the new Harry Potter TV show, I see people say that the child actors are not responsible for their participation. I want to make it extremely clear that is the correct take and no hate or ill will should be directed at the children, but I would like to add that they are not entitled to your financial support either. They have family and a management team that decided this would be a good project for them. Boycotting the child actors as well as the adults is the best way to show that this is a sinking ship of a franchise. The children may not be responsible, but family and management teams around the world need to see that attaching the name of a child actor to a project filled with hate will stain their reputation before they are able to make one. Their management team should be fired and should garner a reputation for making bad decisions regarding projects. Their family should feel as though this was a big misstep in their child's career. Just because they did not make the decision doesn't mean that they won't be profiting from it. Please do not let this boost them to stardom the way it did with the original cast. All that does is demonstrate that it actually does pay to work with hateful bigots so long as you can shift the blame. It's unfortunate, but this should follow them until it's clear that there is no excuse to work with people like JKR and that it will never benefit you. Obviously, I do not condone hate or harassment towards anyone. I think it's ok to express dissatisfaction or disappointment, but in the case of the kids that should be directed at the people making the decision for them, not the children themselves.
The child actors would have already been paid, boycotting the show isn't going to negatively affect that.
What's far more important is the attention and subscription economy. Whatever platform is streaming it, unsubscribe from them and tell them exactly why. Don't talk about the show. Don't endorse watching it, don't discuss with people how it did XYZ different from the books or whatever, fuck the whole thing off. Don't even bother pirating it. Let it fizzle out like a fart on the wind. They're going to pump millions into trying to get you to watch it and you're going to spit in the face of all those executives desperate for your time by refusing to do so.
