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.
You can't vote your way out of communism or islam.
You can't vote your way out of anything. All voting will ever do is let you pick the least bad option from a list made by other people. You want something fixed? You gotta fix it yourself.
