What sorts of things would you consider 'unamerican'?

[Sooga]

Fellow 2p2er Duke was chatting with a friend on AIM, when that friend brought up out of the blue the fact that he hates the Fonz on Happy Days. Duke and I were, of course, aghast, and Duke joked that his friend should be put on a 'no-fly' list for an opinion like that.

So that got me thinking... what sorts of things would you consider just flat-out unamerican? I think hating the Fonz qualifies - I mean c'mon, who hates Fonzie?

Duke suggested hating baseball, but I disagree. Baseball's not for everyone, I can understand that.

He then suggested hating MacGyver, to which I thoroughly agree. Anyone that's got a problem with MacGyver should be executed for treason.

So what are some others?
