Everyone individually, and each can then express their opinion on Facebook’s moral status, and decide otherwise whether and how to engage with Facebook, based on whether and to what extent Facebook aligns with each individual’s moral standards.
(also we're talking about outrage here, not about lawsuits.)
Why do we believe you instead of the other guy? Why does Facebook believe you instead of the other guy? Because Facebook is in the US instead of Iran?
Here's my position: I am a moral absolutist. Still, I don't want a moral absolutist deciding what Facebook thinks is appropriate content. There's too many systems of absolute morality, and too many of them differ from my own in important ways - ways that I'd like to be able to talk about.
However, I get to be morally outraged at their actions whenever it pleases me, and I get to get others to be outraged too and if we're enough people we may convince them to change course.
In that sense, I don't care one bit about the guy in Teheran who thinks being LGBT is wrong and I don't have to.
I'm still worried about the guy who does get to dictate what Facebook will carry (namely, somebody at Facebook). I don't want that person to be very morally absolutist, and I worry that they are becoming increasingly so as time goes by.
There are opinions that I don't agree with that I think are still completely legitimate and perfectly moral.
There are opinions that I take serious issue with and may even find immoral but for which I'd still claim that it's worse to try to suppress them than to allow them.
And then there's stuff like incitement to violence or the president of the USA spreading dangerous lies about an election ... tolerance can only go so far.
Of course, it's a difficult call to make. Of course, no matter what you decide, someone is going to be angry. But you can't just not decide, you do have to take a stand and by refusing to do so, you have effectively already decided something (that's the whole point of Sartre's philosophy btw, which was inspired by WW2).
So what exactly makes your morality absolute? Can you provide any evidence for it? Most people give hand wavy answers to this question, mumbling something along lines of intuition etc, which is not evidence, but as arbitrary and relative as some random choice of initial values for some random moral framework.
It's a fact that different people have different perceptions of morality, but that alone is not a sufficient argument to shut down any debate about ethics.
It is our duty as moral individuals to fight for what we think is morally right. And sometimes we will have to compromise.
But I'm tired of having to argue for why LGBT rights are important (something that I really would have hoped would be understood by now), since that is not the point. The point is that OP gave an example of a decision that "would spark an outrage" and I contended that that would be the case because it would be seen by the outraged as an immoral decision.
You can't take people's rights to be morally outraged away from them. You can, at the most, try to argue with those people why the supposedly immoral thing is not actually immoral, but I haven't seen anyone here doing that: only people defending the truism that "everyone has different moral standards". Which... yeah.
You just make a lot of claims, but you fail to back them up, so they are and remain nothing but that, baseless claims. It's basically just your opinion, which you are trying to wrap in the garment of 'morality'. So if you are moral realist and your morality is easily discarded, why should they care? If you are a moral anti-realist and still make moral value judgments, which are also easily discarded without consequences, why should they care?
Yeah, I know, you're right. Everybody else is sure that their moral framework is right, too. So why does yours get to rule? What is your basis for saying that yours is right and theirs is wrong?
You may in fact be able to give a defense of your moral framework. That defense seems right to you, and to those who agree with you. But defenders of other moral frameworks can do that, too. Which self-consistent and defensible (per the adherents) moral framework should be the one to rule Facebook, and why?
