So words aren't violent action in anyway, because you haven't acted on anything. But offering money is violent enough to be legal even though you haven't paid anyone?
Speech isn't violence because its nothing more than words and our speech is a protected right. Offering money to murder someone is almost certainly illegal because they are doing more than talking, they are choosing to collude in the act of murder and a jury is much more likely to agree there.
My point wasn't that money had to change hands or be offered, I was responding to an earlier comment. A person directly taking part in plotting to commit murder I'd also likely breaking the law and likely to lose a jury trial if they are actively plotting a murder whether money I'd involved or not. Saying "someone should" simply isn't a plot.
But I wasn't saying "someone should", I was talking about a person with a following saying "go kill this person." I said "direct people to kill someone."
Your distinction that money has to be offered seems completely arbitrary. It implies people only do things for money and are otherwise impervious to influence. You really underestimate the level of stan culture America has.
When you believe that is okay and libel is also okay, by your standards, I can tell the world my neighbor is a pedophile who assaulted me as a child, and ask people to decapitate his whole family. And as long as I don't offer money, that's fine.
And yet the former led directly to Thomas à Becket's death and is the classic example of giving direction through indirection. It was much more consequential than an unknown stranger on the internet offering a bounty.
But, strictly speaking, neither of those are threats. In English law, they'd be more likely to be prosecuted as Soliciting to Murder or Conspiracy to Murder - I imagine there are similar offences in America.
Vaguely saying "someone should" is very different from offering a bounty or plotting to do it yourself.
