But when a couple of TSA agents start smirking and making comments and whispering their whatevers when the hot young girl went into the full body scanner as I mentioned in my thread recently .. then I question the quality of the people we have manning these things.

TSA agents monitoring the scanners should be able to see the scanned images, and only the scanned images. They should work in some sort of enclosure that prevents them from knowing anything about a passenger other than what the scanner reveals. The offensive behavior Dan describes would be eliminated if the agents hadn't seen the young lady before she entered the scanner. The scanner may show an image that's recognizable as a 5'6" female, but it doesn't show whether or not she's attractive. She could be a movie star or your Aunt Bertha. If an agent is going to drool over one woman's scanned image, it's going to be because he decided she was a hottie before she walked into the machine.
