David Asman used Ron Wyden to claim that all Democrats must either agree with destroying medicare or be considered extremists. I would respond to that by pointing out the lack of unification in the Democratic Party, because we don't take away the personal freedom of party members. Republicans on the other hand are pressured into signing pledges and taking back statements of truth. (Remember the 24-hour turnaround in which Secretary. Rice said she didn't "literally" mean that the Bush Administration had made mistakes?).

"I got groped, but I didn't get irradiated."

Correction: You didn't get fully irradiated. The x-rays bounce around pretty well. It's like when a dim lamp is on; you can still see light from objects that aren't directly illuminated. Maybe there's some good shielding (I haven't flown since 2004), but if not, everyone in line is getting a small dose while they wait.

I had a physics professor who got tired of dental x-rays in his 60s (since his teeth were clearly not going to suddenly start moving at that age). He convinced the dentist to stop by telling her how her protection from direct exposure doesn't cover everything; x-rays can bounce off any concrete in the building and do a sort of ricochet trick shot to hit the person operating the x-ray machine.
