I cannot accept to carte-banche dismiss an entire demographic. Even if their solutions are evil & horrible, the problems which brought them to the streets are still real. Secondly, to simply dismiss them offers them no alternative to the racist solutions their leaders promote.
In 2008 the economic system broke down, elites saved themselves and put the pain on the common people, triggering a new populism.
I fear the "migrant crisis" may have been engineered to redirect this popular anger.
