Letters to congress

[Triple Zero]

Trip, I understand the concerns you raise, but:

1) I am writing from the traveller's perspective, and unless they rub plutonium onto my skin, 10 seconds in a backscatter machine is waaaay less toxic than the amount of carcinogens I absorbed merely getting to the airport that day, and

I'm going to have to use Trip's argument on this one, and say that you have absolutely no idea how much damage the backscatter is doing in proportion to all other toxins and carcinogens in the environment.

Exactly, we don't know.

2) In the case of political letters, I'm not above making sweeping generalizations if it helps me get to my main point.

How about dripping sarcasm?

Substitute "complain" with "voice my concerns regarding"?

Yeah, that'd work.  Striking "to complain" and you'd have "writing to you about" which would be alright as well.

how about "this is in regards to my concerns"

[Phox]

it is simply a fear driven slight-of-hand designed to establish an illusion of safety.

It's "sleight-of-hand". Otherwise, i like it. Lots of good suggestions.
