Neo Nazis etc will rise whoever gets into power...its a natural response to flood of migrants.(humans--innocent good bad and indifferent) Not an easy solution (oops that's a loaded word).
Gert Wilders in Holland is similar in fighting Islamification which the migrant problem is fuelling.
I am afraid you could be right fish, people are frightened of losing their identity, they see support given to these growing communities by the state, the various cultures demanding more, yet not wanting to intergrate, in fact refusing to intergrate, the authorities frightened to act as in Rotherham, the pedophiles supporters cheering them when they shouted Allahu Akabar on being sentenced, what an accolade for a religion when child rapists are supported by some members of their community, any normal person would be sickened, I am sorry but I view the whole Muslim religion as an insidious fifth column, there I've said it.
