By all means, say whatever you want. Just don't expect to be allowed into the USA as a right.
The irrationality and absurdity of TSA is something that most Americans are aware of. But we have a President and Congress who think it's all just fine. The only solution to this problem is to elect lawmakers who will abolish TSA. Last time I checked, there's only one candidate for President who has included that as part of his platform.
No, voting in different lawmakers is not the sole recourse of citizens of a democratic country. Raising awareness so that your existing lawmakers notice the issue sufficiently to get back the ass coverage stage is far more effective than electing somebody who's saying the right words and will then turn around with a "So long, suckers!" as soon as he's got your vote. Not that that has happened recently, of course.
Erm, actually it's not "single-issue voting." There is a whole host of bad legislation that is very invasive of personal liberty in the US, not just TSA. A good example would also be the recent SOPA/PIPA legislation. All those things need to be voted down, not just one of them.
