My personal hunch is that the bulk of the people who reside in the "anything to keep us safe" and if you don't like it, you should drive camp are the large majority of americans who never fly, and hence don't know what they are talking about/will never be harassed by the TSA.

"...fraction of Americans who travel by plane each year is in fact probably not more than about 1 in 3.
In addition, these flights are concentrated among relatively few people. A study by the market-research firm Arbitron found, for instance, that frequent fliers — those who take 4 or more round trips per year — account for the 57 percent majority of all air travel, even though they make up just 18 percent of air travelers and something like 7 percent of the overall American population."
If any of you have more accurate data by all means share it.
However, back to my point, and i can't prove it, it is just a hunch, but i suspect that a large portion of the people that take this attitude don't fly (let alone are required to fly for their livelihood), and do not have to put up with this.
To put the statistics above another way. 7% of the u.s. population puts up with more the half of all the hassle of dealing with the TSA....So if you are are not part of the minority of americans forced to put up with this constantly its easy to take that position...you have no skin in the game...
