Oomis, those you describe are definitly not zonas, but they just as definitely they are prutzas. Uncovered knees getting into a car or uncovered elbows most definitly falls into the category of a prutza. “
And I could not disagree more. A prutza is a very definite type of immoral woman (or man for that matter), who ACTS as well as dresses, in a way that is utterly contrary to the spirit and letter of the Torah.
If you believe that someone is immoral because they dress a couple of inches too short to suit your sensitivities (and I believe firmly that they SHOULD dress b’tzniyus, but I would mever condemn them for not following my standard), then you really have no concept of what immorality is. I know people who believe it is untzniusdig for a BABY GIRL to dress in sleeveless clothing in the summer.
Time to find another topic. And I think the one about people who double park, blocking cars from leaving, or people who act like bulvanim in stores or restaurants, are a much worse chillul Hashem than an exposed inch of throat, elbow, or knee.
