I don't see why the percentage is super significant. If the reason they are on the list had to do with their ethnicity, it's still bad and something that should absolutely be addressed.

Like 90% of the runtime of old racist Disney movies are fine and don't contain racial stereotypes, but that doesn't absolve the remaining 10% in any way, and if the movie was twice as long, the 5% of remaining insensitive content wouldn't be more justified.

So they have an asshole list of "funny" names. When they get caught they argue that most of the people they are racists towards are white, So it's fine? White people can definitely be racist towards other white people, you can easily find examples of that in Europe, so that is definitely a thing. As an ethnic Norwegian, I'm not impressed over doing the list in it self, and then doubling down on the racism towards us by pretending it isn't. That makes it way worse.
