Racism was not a problem on the Discworld, because - what with trolls and dwarfs and so on - speciesism was more interesting. Black and white lived in perfect harmony and ganged up on green.
Interpretation
The quote highlights how in the Discworld, issues of race (racism) are overshadowed by a more complex form of discrimination based on species.
In this quote, Terry Pratchett uses humor and fantasy to explore themes of prejudice and societal division. On the Discworld, where various species coexist, the focus shifts from traditional racial divides to the more intricate dynamics of speciesism, suggesting that different forms of discrimination can arise in various contexts. This implies that even in a world where racial harmony exists, new divisions can emerge, forcing a re-evaluation of what society perceives as important issues.
In practice
During a discussion about social issues in literature, one might quote this to illustrate how fantasy can reflect real-world problems.
And then Jack chopped down what was the world's last beanstalk, adding murder and ecological terrorism to the theft, enticement, and trespass charges already mentioned, and all the giant's children didn't have a daddy anymore.

And lots of other people. But everyone apart from them. It's a very enlightened civilization.

People look down on stuff like geography and meteorology, and not only because they're standing on one and being soaked by the other. They don't look quite like real science. But geography is only physics slowed down and with a few trees stuck on it, and meteorology is full of excitingly fashionable chaos and complexity. And summer isn't a time. It's a place as well. Summer is a moving creature and likes to go south for the winter.
The Tao teaches us not to intervene and interfere. The things we love we have to learn to leave alone. And the people we love we have to learn to let them be.

Sometimes I get the feeling that we're just a bunch of habits. The gestures we repeat over and over, they're just our need to be recognized. Without them, we'd be unidentifiable. We have to reinvent ourselves every minute.
