And that is exactly right. Among other things, most slurs, like the one here, fade away quickly. In a week very few people will remember any of this, and in a couple of months it will most likely completely disappear from the public consciousness.
But if a defamation suit is brought, the slur will continue to pop up in public sources as long as the litigation is around to be reported on.
