That's one reason I haven't re-visited the US: I don't want to have to deal with all their fucking bullshit when you arrive. All countries have secuirty checks and stuff that don't always make sense and seem an invasion of your privacey, but the US seems to go all out and take it to a new level.
Just for comparison, I always got the impression that Australia was quite strict and uptight, particularly when it comes to Customs. But when I went it was pretty layed back, they didn't even check that I had nothing to declare, the customs guy didn;t seem like he really gave too much of a fuck. There was even a mistake on my temporary visa thing (passport number had a typo so it didn't match the number on my actual passport) that only cost me a few minutes delay, and when they reliased it was just a typo they were like "Oh right..yeah whatever, go ahead." I know people who've been stuck for hours upon arrival in the US for less.
