Even assuming he had his way on this issue the notion that it would lead to the arrest of someone who was born in this country to immigrants is absurd.
Just as it was absurd that Hitler really did mean his words when it came to Jews or that the Jews who was consider by most Germans as solid citizens at the time would ever be allow to be treated as Hitler wish them to be treated.
In any case Finn my friend that is what "they" are asking the right to deport anyone who had parents here without paperwork and it is not just one man but also a group of men some of who are also in the US congress with him that are trying for this silliness and evilness.
Paul does indeed wish to deport US born citizens who happen to had been born of illegal immigrates and he only retreated somewhat from his words on the civil rights acts when hit by a tide wave of complains over the matter.
Yes, he cannot really mean what he is saying any more then Hitler could now could he and his supporters.
