Time, I think, for another classic Guardian sentence. A headline, in fact: 

How can our future Mars colonies be free of sexism and racism?

The author of this latest ostentatious fretting session, Martin Robbins, is concerned by the “white and male race to conquer Mars.” The rest is pretty much what you’d imagine: 

The first woman to be raped in space has probably already been born.

And, 

The only population on Mars that we know of is a handful of rovers, but no doubt we’ll start a war anyway, before dragging them into some form of slavery or oppression. It’s just what we do.

And so on, and so forth.
