They're leaving the union , not the planet . Britain needs to be Britain and not another forced melting pot as some outsiders want it to be . Why do some people want every white majority country to be a diverse multi cultural society and tries to force said country to adapt to immigrants as opposed to immigrants adapting to the country they moved to . Nobody is asking other ethnic groups to evolve their way of life to accommodate new comers . What about Japan , Iran , China among others with strong cultural histories . When whitey gonna be able to move to Tehran and have the wife wear a bikini poolside ?
