I'm sorry, you think you're very rational. Immigration is not a gift. It is something that happens and so called States use force to counter that when they don't like it. It's also not a right to not have migrants, it is something you enforce with power police and military. If there are reasons for migrants to be statistically more violent then maybe it's not about their genes but about the system they are put in, the place they get in society, the mismatch with the culture they are coming from and most of all, the lack of active integration. So you don't "have" any rights to deport: you "enforce" deportation. You don't take a statistic done now and apply that as a theorem to justify your racist views. Everything must be understood with context in mind. I can really tell that 100% of people arrested for violence are more violent. Yet this must create no prejudice about the prison population. Turning statistics into prejudice is exactly what fascism is about. Closing the eyes in front of people in need for the needs of the privileged ones, with the violence and entitlement given by the power of government. 100% fascism.
