I've just watched the Aquarius refugee ship dock in Spain being turned awy by right wing governments and being accepted by Spain's Socialists

"The Maltese government is described as a social-democratic party."

Described maybe - it's policy towards immigrants belies that
It sure ain't socialist - closer to May than it is to Corbyn - New Labour maybe

So they're refusing to accept the refugees because of their political affiliations, and you can tell what their political affiliations are by watching how they deal with the refugees.
That seems a rather circular form of logic.
