Of course I would feel prosecuted if I was called to register just based on my ethnicity, complied, and then was detained in extremely poor living conditions.
So, if it just an inmigration affair, why not rounding up Eastern of European illegal aliens?, you can bet there are lots of them with void visas and warrants.
If it is a War on Terror affair? Why not saudis, why iranians who can be jew or refugees form the iranian revolution?
So, you are eager to approve the equation
(muslim-middle eastern-arab-whatever) + expired visa=terrorist
go ahead just don't cry when they grab you for something else and no one gives a damn (firearms mandatory registration anyone? c'mon everybody knows those gun nuts are a bunch of paranoid militia wackos...)
