"Inciting a riot" is no different from any other kind of speech. We're not talking about mind-control here, overriding the listeners' will. You speak and other people decide how they will react. They remain responsible for their own actions, just as you are responsible for yours. The difference is that your actions were limited to mere speech, which does not justify any kind of forceful response, whereas theirs involved assault, theft, destruction of property, etc.

That's clearly ignoring human nature, which includes crowd effects that are well-documented and unrelated to 'the listeners' will' or 'deciding how they will react'. Best to read up on this, before saying silly things.
