There is a difference between a character in a video game saying "kill all the haitians" and somebody actually suggesting you kill haitians in real life.
Slight difference. Not that much to mean anything though.
Incitement to commit violence is incitement to commit violence. It doesn't matter whether I say it about one individual while part of a crowd or say it about a group of individuals from the comfort of my own home: if I endorse violence in real life I should be held accountable for the consequences of my endorsement.
Yes, in civil courts, after someone has done a crime as a result. Protection of free speech requires that tolerate some hatred in books and speeches.
