Oh for the love of fuck. Americans. Your country isn’t the centre of the universe. It doesn’t matter where a company’s headquarters are. If you are doing business in, for example, Germany, you have to abide by German laws. Being American isn’t an excuse and it doesn’t shield you from consequences for breaking the law.
Also, the big issue is that Valve isn’t actually using their right to refuse service. People can spread all sorts of bigotry via Steam’s discussions and groups without Valve acting on it. They’re providing a platform for hate speech and that is inherently immoral, regardless of what the law says.
But Fukushima did render a fairly large area uninhabitable, and the ongoing cleanup is still costing billions every year.
Also, there’s still no solution to nuclear waste beyond burying it and hoping that no one digs it up.
Renewables exist, and, combined with upgrading the grid and adding sufficient storage facilities, can provide for 100% of electricity demand at all times. Without any of the risks associated with nuclear power (low as they may be, they exist), and without kicking a radioactive can down the road for hundreds of generations.
