You're welcome to your opinion. But you also have to take responsibility for it.
There are countless millions of people with no careers at all. Clearly, our society doesn't believe in a right to having a career at all, let alone a right to keeping one's existing career.
If we're worried about the threat to PewDiePie's ability to make a living, to his life, liberty, and pursuit of happiness, it seems like the fundamental problem is not with people on the internet having opinions, it is with the system where losing a career threatens all those things. Fix capitalism, implement a UBI, whatever, and then his loss of a career wouldn't seem like a threat to his ability to live a fulfilling life or to reach an effective means of speaking to people.
The same argument can be used to say, "Your opinions have consequences. In this case, shutting down the TSA's security theater program put a lot of TSA agents out on the streets. You have to take responsibility for it." Or "In this case, Edward Snowden almost ruined the careers of many NSA spooks who could never make it in the private sector." Or many similar things. Would you agree those are bad arguments for not fixing the TSA or reforming the NSA?
Just like no one gets to decide what kind of jokes are allowed to be told, no one gets to decide how someone reacts to those jokes.
We do have a serious problem that someone can say things in what feels like private, to what feels like a private audience, and they can attract a global audience very quickly. I said lots of dumb stuff both in person and online (on AIM or Xanga or something) as a teenager, and those are gone from the internet and that is very good. That seems to no longer be true for today's teenagers. I'm worried about this, and I'm specifically worried about the inevitable media circus once the generation that grew up on Facebook and Twitter starts running for elected office. Democrats will be vilified for liking Ayn Rand for a few weeks in 10th grade; Republicans will be vilified for liking Karl Marx for a few weeks in 11th. If you remember the hullabaloo over that one Bernie Sanders college essay, imagine that, 24/7.
But I don't see the "destroyed their career" argument being applied to teenagers; I see it being applied to people who basically have communication as their job. PewDiePie's entire career involves making as many people as possible watch him talk about things. Of course people are going to have opinions on what he says, and of course his career is going to be affected by whether the general public likes what he has to say. That's the career he chose.
Yeah, and people saying "Death to Jews" managed to murder six million of them. Yet apparently you think that is funny and beyond reproach, while taking issue with it is a serious problem.
Example: If an anti-vaxxer published their opinion in a private blog, you'd probably be OK with their speech (as misguided as it is). If the same person started promoting their "opinion" using a national newspaper, you'd be a lot more upset.
Moreover, it's documented that the WAJ article authors went after PDP's livelihood directly (they contacted youtube and Disney, PDP's sponsor) with their allegations and were successful when Disney dropped PDP and Youtube cancelled PDP's new show!
But should pewdiepie be punished for it?
What the articles critical of PewDiePie are saying is, "here is what he said and why we think it is offensive and why we no longer watch his channel. If you agree with us, you should also not watch his channel"
Everyone is free to read this opinion and then decide for themselves if they agree with the writer, or if they want to keep watching. If it turns out that so many people agree with the articles that PewDiePie no longer has an audience large enough to sustain him, then that sucks for the people who DO want to keep seeing him, but is just reality. If not enough people want to watch content of a certain type to sustain the producer, then that content will not be produced.
I don't think this is quite what you're saying, but "Why is your definition better than mine" reminds me of a lot of discourse I see about free speech, where free speech is an inherent virtue, and you should be able to say whatever you want to say without anyone doing anything about it - neither censoring it, nor objecting to it, nor listening to it with a critical ear or responding with anything other than "Yay, speech."
This seems to me to be the most fatal form of censorship. We're essentially sandboxing speech. Say whatever you like, as long as it doesn't actually mean anything. Participate in public debate, as long as it doesn't change. Respond to others, as long as you don't dare to claim that any idea might be wrong. What is the point of free speech in such a society?
If all ideas are equally valid, or at least the ideas of the inside crowd are valid and outsiders get a "who are you" response, why do we even try to have a democratic society? Just let the king do what the king wants, or the CEO do what the CEO wants. Comment and criticize all you want, as long as it doesn't have an effect.
But if we believe in there being a point to free speech, we should respond to speech with "Why do you believe that, and can you try to convince me that I am wrong while I try to convince you that you are wrong" instead of "Who are you to disagree with me".
