Or, don't travel by plane in the US
If you read the article a bit more carefully, you'll see that this is about people traveling inside the US -- so for instance from Chicago to Los Angeles, etc.
This has nothing to do with 'travel to a country blablabla'.
Most of the outrage is coming from US citizens, traveling inside the US. In the United States, this approach has become the standard -- go through a machine, or get patted down thoroughly by a human.
Although I'm a frequent flyer, i've gone through the full body scanner maybe two or three times in the last year. The other times is just the plain old metal detector.
Just make sure you don't hit the metal detector when you go through it, or it'll throw a hissy-fit (accompanied by much groaning from the biz travelers behind you).
I'm suspecting that only outside of the rush hour these machines are operational. When the business man / woman / individual needs to go through security in a hurry (monday mornings, thursday evenings anyone) at least at the airports I travel through don't have the full body scanners working.
And rebooting these new-fangled things is apparently a pain -- not a quick shutdown, it takes at least 10 mins, last time I saw it happen.
