Once they've gotten the government the "right" to declare someone officially "un-American" by stripping his citizenship, the next step is to declare that the rights protected in the constitution extend only to US citizens. This, then, makes for an interesting case where the government can declare you a terrorist for exercising your rights, revoke your citizenship, and then claim you no longer have those rights. Then you can be jailed for expressing your opinion.
I've gotta admit, these guys are thorough...ly disgusting.
