Rights/liberties necessarily limit each other where they conflict. A right to be unharmed, for example, may limit freedom of expression.
Beyond necessary limits, principles don’t need compromises. The linked harm principle explains a well-recognized, necessary limit.
In practice, it’s treated as narrow limits on incitement to imminent, lawless action; deprivation to peace & privacy; defamation; violation of intellectual property. Basically, anything that directly harms no matter if ignored.
In contrast, merely offensive expression can simply be ignored (or reciprocated with expression of any kind) without conflicting with rights, so it doesn’t need to be limited.
Thus, terroristic threats or targeted, persistent threats (that put a reasonable person in fear of their safety, thus depriving their rights) aren’t protected. Neither are false claims that deprive them their livelihood nor false warnings that cause panic & reckless endangerment.
Blanket statements that vilify a group of people, ill wishes, falsehoods that don’t incite immediate action, etc, don’t directly raise conflicts that necessitate limits.
Is the harm directly from the speech? Ideas aren’t actions & uncritically harming people is a choice.
We’re all capable of reading stupid shit then taking it upon ourselves to harm people. Yet how many of us do? If I harmed someone, I wouldn’t consider shit I read & uncritically acted on a valid excuse. I’d consider failure to think in the least bit critically before acting a total & culpable lapse in judgement.
Should we not hold every thinking person to that standard? Do you hold yourself to a different standard & think that would be a valid excuse?
