"Freedom of speech isn't freedom from consequences!" is one of the most infuriating lines I've ever had the displeasure to hear parroted. What else could it possibly be, but the general idea of not being punished for saying things? The only thing that matters to the principle of freedom of speech is those consequences.
Who cares whether it's a government that decides that when you express a certain opinion, you lose your job- or twitter?
Funny, but not surprising, how even self-proclaimed leftists will side with capital when it's treading on the right people.
You might say "but you can't force people to platform/associate with those they find odious!", to which I reply 'of course you can'- there's laws against unlimited free association, with the argument that bulk group dynamics end up diminishing individual freedom on net.
You might say opinions are a different category from e.g. ethnicity, as they can be changed, while race can't.
In that case, in the future when we can change our bodies in a day, will it be alright if 'race', no longer existing as such, becomes as acceptably targetable as speech?
