I'd be happy to have a civil conversation with you.
I disagree with the following points you made, for the reasons listed:
These days we aren't really hung up on who is an actual white supremacist and who isn't.
The problem I have with this statement, is that you seem willing to label Notch a white supremacist or allow him to be labeled one, when there is, in my mind insufficient evidence that he actually is a white supremacist. You and I might disagree on whether merely uttering the phrase "it's OK to be white" would constitute sufficient evidence that someone is a white supremacist.
That's all part of the game, the plausible deniability and the "it's just memes/trolling liberals" argument.
Who cares? He's repeating the shit those people say, doing stuff that makes life difficult for people with actual problems, unlike Notch who is a billionaire.
The problem I have with this statement is that it assumes that Notch is using the phrase "it's OK to be white" to troll, or as a meme. He might be, which is something I'd disagree with. Looking at his other tweets, though, my assessment is that he's not really a provocateur. In one of his other tweets that sounds bad (much worse than this one), he was clearly responding to a provocation, and parroting words back to the person provoking him. I would have to have more context for the situation immediately preceding this tweet to make a judgement. I haven't been able to find out if there was some discussion going on before this or not. But I've seen examples where, in response to some racist comment about whites, retorting with "it's OK to be white" would be a nice way to highlight the racism of the other person.
With regards to "doing stuff that makes life difficult for people with actual problems", I have some issues with this also. Notch is a human being with actual problems, even though he's a billionaire. It is true that his money solves a big set of problems that other people have to deal with, but it's not a panacea (and introduces its own set of problems). I realize he'll get little sympathy, but he's been public about some of the issues of extreme wealth. And I don't think saying "it's OK to be white" actually makes life difficult for anyone. I hesitate to put words in your mouth, but maybe you think this phrase marginalizes other people's problems by refocusing an argument about race and oppression on white people and the problems they might have? Could you clarify what you meant?
With regards to "repeating the shit those people say", I think this is a just a shorthand way of dismissing the actual concept of what Notch tweeted, using guilt- by-association. It seems to me to be a logical fallacy, and a form of ad hominem response. Even when a white supremacist says "it's OK to be white", they are saying something true as a standalone statement (or at least I believe so). If you believe they are conveying with the statement some additional message (the "dog whistle") that is unpalatable or unreasonable, you should state that. I can imagine some ideas that a white supremacist would have that would go along with the saying, that I and many other people would object to. But I don't think it's fair to attribute those ideas to Notch, unless he states them himself. This is because he may have other motives for saying the phrase than the ones you are thinking of.
It's kinda pathetic really. A billion in the bank and the best he can do with his life is spout this shit on Twitter.
And finally, how do you know that all Notch is doing with his life is spouting on Twitter. The problem I have with this statement is that it seems like a caricature of the man's life, with no actual knowledge to back it up. What percentage of Notch's life is spent on twitter? And what percentage of his twitter presence is spent spouting stuff you consider "shit"? What percentage is spent building orphanages in third world countries? What do you know about Notch? I've seen literally hundreds of Notch's tweets over the years (my sons and I are big Minecraft fans), and I've only seen a few tweets that I would consider controversial. So again, in terms of evidence, I don't find what you're saying supported by the evidence I've seen. But if you have additional evidence, I'd be happy to look at it and reconsider my position.
Regards.
