Inciting violence is certainly an arrestable offence, and likely convictable. What hill are you trying to die on?

The hill where take a dim view on and investigation are distinct from charging and conviction, because they are.

You would also have to contend with the problem where you've decided that it is incitement, as if conviction is a formality, even though:

- investigation

- charging

- court process

all come before conviction, which is convenient but not particularly bright or persuasive when they're mentioned in the comment you replied to.
