Over the last few days in France, student protesters, especially in ethnic neighbourhoods, have been demanding more funding and more teachers.
The rioters - as opposed to the protesters - were mostly sub-Saharan and North African. At least 65 education staff have been injured, as well as 170 pupils and 300 officers. There have been nearly 2000 arrests so far.
British Movement have warned that a combination of economic distress and diversity would lead to violence in Europe. This is not a deep philosophical point: diverse societies are inherently dysfunctional, low trust, and prone to outbursts of violence, requiring severe repression to maintain the peace, as was the case in Syria and Iraq before US intervention, and as is the case in Singapore and the UAE. Violence is more likely in times of economic distress.
