Extremist rallies, far-right organised groups and racist dog-whistling have been regular features of the news over summer (and, well, for more than a year). But what looks like a clear-cut case of racism to some is often described in the news with vague terms: "protests", "activists" or "extremist".

And when a person is called racist, it's often strongly refuted. Late last year, Sky News presenter Rowan Dean threatened legal action against anyone who suggested on social media he was racist, among other descriptors, after his co-host Ross Cameron was sacked for racist comments about Asian people.
