There is a legal definition to fall back on in the case of inciting violence, and what Kanye said doesn't come close. Not that Twitter is obligated to hold to that definition, but I think it's pretty misleading to say you are for "free speech" and then define "inciting violence" so broadly as to have virtually no meaning.
