But you're also conflating terms: criticism is not an incitement to violence. An incitement to violence is specific: "I think it would be great if some implied violence happened to that group I don't like".
It's specifically not considered ST to say something like "I hope some legal consequences happen to this person who I think is committing crimes" because amongst other things, that's a call to the application of the justice system, not terrorism.
It's also worth noting that other incitements, like encouraging someone to commit suicide has been found to be a punishable crime - and this is the sort of action Kiwi Farms specializes in and openly supports against their targets.

Plus, the "terrorism" aspect seems to apply to a wider group, or who else is terrorised? Presumably, individuals or groups with similar principles.
Your example also doesn't incite violence, just heavily implies it.
