Last year Sweden had some really high power prices and part of the problem was that multiple reactors where shut down for extended periods of time.
Its not an attack on nuclear, it's a defense of wind. No system is perfect and you can't say that wind is unreliable and then ignore that we had reactors be shut down for multiple months.
The message isn't to stop people from being racist. It's to stop the racists from being part of their fanbase. Macho sports are really susceptible to concentrations of assholes and they need to be actively discouraged or they will take over.
