Alarmist? Yeah. But partially/mostly true? Also, yeah. More and more, it scares me to think that (eventually) there will be another big terrorist attack, and if (god forbid) anyone with certain dictatorial tendencies happens to be in power, he/she could do all sorts of nasty stuff. I mean, we could have our own Reichstag burning down, and then maybe the president declares a state of emergency and hauls off a whole bunch of left-wing media folks to Guantanamo. Whatever.

The president can do this! A possible scenario (and correct me if this can't happen):
(George Bush and I are playing ping-pong somewhere on his big Texas ranch, on one of his many many holidays)
Bush: How many points do I have?
Me: Four.
Bush: No, I have five.
Me: No, it's four. We've played eight points, and we both won four of them.
Bush: No, I have five points.
Me: No, you have four.
Bush: I have five.
Me: Okay, fine. You have five.
Bush: Are you saying that because you want it to be five, or because I really have five?
Me: I don't know! You've got four! Five! However many you want to have!
Bush: I don't believe you. You're an enemy combatant!
(the Secret Service guards whisk me away to Guantanamo, where I remain for the rest of my life, without charges or trial. Waterboarding is a distinct possibility.)

So the only thing that's impossible in that situation is that, in reality, I wouldn't have let him win ANY points. But in all seriousness, it is creepy.

Furthermore:
Jews <--> Islamic extremists (in a less politically correct world, this might just be "Muslims")
concentration camps <--> Guantanamo
Enabling Act of 1933 <--> Patriot Act
Do we want to wait for more pretty obvious parallels?
