Sneako has no idea what the supposed grievances of rioters are in France, just like he knew nothing about Ceuta when he cheered for its invasion by Africans.
He sees people like him destroying a functional White country that deep down he knows people like him could never build, and he sides with the destroyers. Pure resentment politics.
You cannot fix this with better arguments or "Western values", you just need to keep these people out of your country and work to disenfranchise everyone who shares these instincts.
