You should be able to go online and do that. And even if you did not the game would do that for you if you were out (giving you a choice of what machine to get rid of). Or at least that's my impression of the DRM.
Because there might not have been any "slant" to start with. I'd have to read the originals but from what I've seen so far it's more a "let's blame the left while sticking our ideology into school" move.
Well if the DRM were tripped in a legal game then that would be a buggy mess...
EDIT:
I'm not saying that was the case but a similar thing was done with ARMA II and it had some issues with its Fade DRM system going off when the person was using a legal copy.
