You've actually asked two different questions:
It's not illegal to be racist or make racist remarks, in her case she was making a statement prejudiced by her racist views. That's not unlawful.
I think you are being pedantic. I don't know why. My question wasn't a trap! The whole thrust of the defence is encapsulated in the phrasing I gave. And I am simply asking, if Sam Kerr had actually said something along those lines, would posters find that racist.
(The phrasing I posted was "I think you are a stupid man who is treating me less favourably because of my skin colour and is displaying white privilege")
