I genuinely understand your misgivings about the TSA questions you on personal matters; however, since the TDC is talking to thousands of people everyday, your answers will not be logged or remembered. What matters is how you answer. Your body language helps the TDC to determine if you are a threat. If you maintain eye contact and exude calm body language you will be through in no time, and you can be sure the government will not have recorded your responses. While on its face this program appears to invade privacy, in reality the intrusion is very small.
