How much foreign scum
You are foreign scum. As for your question as many as your polictical leaders want. Is not as if there is some obstacle to stop people coming, it is a political decision. That is all, there is no political will to change it.
Calling those people scum you shoot yourself in the foot.
Nobody will listen to a hateful little racist. You need to tune your arguments better not everyone is a fat looser with no future looking to vent his frustration.
