Acts of violence are labelled differently depending upon the perpetrators. But it’s not ‘two-tier’ the way the racist politicians want us to believe. Extremist acts by white right wingers are not treated with the same seriousness as they would be by other (most specifically Islamist) groups. Downplaying the threats posed by racists has led us to the state we’re in, and is one of the root causes of the past week’s riots.
