I feel like this would be a solid 4D Chess Strategy. White Nationalists pop-up in "solidarity" with the Muslims by also converting to Islam. Then, the new White Muslims start conversing with their non-White Muslim brothers about how best to make UK more of a Muslim country. Then convince the non-White Muslims to start promoting more traditional Islamic Values/Beliefs in the UK, while the newly converted White Nationalists merely show support for their Islamic brothers.
Could be entertaining.
They would just continue to target Whites for our race. You are vastly over estimating how Islamophiliac the UK is. Starmer's wife is a Jew, and Labor just purged Corbyn for anti-Semitism. They tolerate unrest from Muslims strictly as a weapon against Whites.
