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.
